+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions

+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement

+our extensive community's collective experience, and from the sponsored
+contributions of individuals, research groups, and commercial organizations.
 
 ### Built to Adapt
 
-...
+After more than 5-years of integrating with many companies and organizations,
+The OHIF Viewer has been rebuilt from the ground up to better address the
+varying workflow and configuration needs of its many users. All of the Viewer's
+core features are built using it's own extension system. The same extensibility
+that allows us to offer:
 
+- 2D and 3D medical image viewing
+- Multiplanar Reconstruction (MPR)
+- Maximum Intensity Project (MIP)
+- Whole slide microscopy viewing
+- PDF and Dicom Structured Report rendering
+- User Access Control (UAC)
+- Context specific toolbar and side panel content
+- and many others
+
+Can be leveraged by you to customize the viewer for your workflow, and to add
+any new functionality you may need (and wish to maintain privately without
+forking).
 
 ### Support
 
-...
+We offer support through
+[GitHub Issues](https://github.com/OHIF/Viewers/issues/new/choose). You can:

-# Architecture
-
-Looking to extend your instance of the OHIF Viewer? Want learn how to reuse _a
-portion_ of the Viewer in your own application? Or maybe you want to get
-involved and draft or suggest a new feature? Regardless, you're in the right
-place!
-
-The OHIF Viewer aims to be decoupled, configurable, and extensible; while this
-allows our code to be used in more ways, it also increases complexity. Below, we
-aim to demistify that complexity by providing insight into how our Viewer is
-architected, and the role each of it's dependent libraries plays.
-
-## Overview
-
-The [`OHIF/Viewers`][viewers-project] project contains the source code for the
-OHIF Medical Imaging Viewer. It is effectively a React [progressive web
-app][pwa] (PWA) that combines the business logic housed in
-[`OHIF/ohif-core`][core] and the components in our React Component library
-[`OHIF/react-viewerbase`][component-library]. It provides customization for
-common use cases through [configuration][configuration] and for adding
-functionality via [extensions][extensions].
-
-### Business Logic
-
-Our goal is to maintain the majority of our business logic in
-[`OHIF/ohif-core`](https://github.com/OHIF/ohif-core). `ohif-core` offers
-pre-packaged solutions for features common to Web-based medical imaging viewers.
-For example:
-
-- Hotkeys
-- DICOM Web
-- Hanging Protocols
-- Managing a study's measurements
-- Managing a study's DICOM metadata
-- A flexible pattern for extensions
-- [And many others](https://github.com/OHIF/ohif-core/blob/master/src/index.js#L49-L69)
-
-It does this while remaining decoupled from any particular view library or
-rendering logic. While we use it to power our React Viewer, it can be used with
-Vue, React, Vanilla JS, or any number of other frameworks.
-
-### React Component Library
-
-[`OHIF/react-viewerbase`](https://github.com/OHIF/react-viewerbase) is a React
-Component library that contains the reusable components that power the OHIF
-Viewer. It allows us to build, compose, and test components in isolation; easing
-the development process by reducing the need to stand-up a local PACS with test
-case data.
-
-[Check out our component library!](https://react.ohif.org/)
-
-### Misc. Extensions
-
-Want to add custom logic or UI Components to the OHIF Viewer, but don't want to
-maintain a fork? We expose common integration points via
-[extensions](./extensions.md) to make that possible. For a list of extensions
-maintained by OHIF,
-[check out this helpful table](./extensions.html#ohif-maintained-extensions).
-
-If you find yourself thinking "I wish the Viewer could do X", and you can't
-accomplish it with an extension today, create a GitHub issue! We're actively
-looking for ways to improve our extensibility ^\_^
-
-[Click here to read more about extensions!](./extensions.md)
-
-### Diagram
-
-This diagram is a conceptual illustration of how the Viewer is architected.
-
-1. (optional) `extensions` can be registered with `ohif-core`'s extension
-   manager
-2. `ohif-core` provides bussiness logic and a way for `viewer` to access
-   registered extensions
-3. The `viewer` composes and provides data to components from our component
-   library (`react-viewerbase`)
-4. The `viewer` can be built and served as a stand-alone PWA, or as an
-   embeddable package
-   ([`ohif-viewer`](https://www.npmjs.com/package/ohif-viewer))
-
-![Architecture Diagram](../assets/img/architecture-diagram.png)

-
-## Common Questions
-
-> When should I use the packaged source `ohif-viewer` versus building a PWA from
-> the source?
-
-...
-
-> Can I create my own Viewer using Vue.js or Angular.js?
-
-You can, but you will not be able to leverage as much of the existing code and
-components. `ohif-core` could still be used for business logic, and to provide a
-model for extensions. `react-viewerbase` would then become a guide for the
-components you would need to recreate.

-# Extensions
-
-Extensions add new functionality to the viewer by registering one or more
-modules. They go one step further than configuration in that they allow us to
-inject custom React components, so long as they adhere to the module's
-interface. This can be something as simple as adding a new button to the
-toolbar, or as complex as a new viewport capable of rendering volumes in 3D.

-
-## Overview
-
-At a glance, an extension is a javascript object that has an `id` property, and
-one or more "module" methods. You can find an abbreviated extension below, or
-[view the source][example-ext-src] of our example extension.
-
-```js
-export default {
-    /**
-     * Only required property. Should be a unique value across all extensions.
-     */
-    id: 'example-extension',
-
-    /**
-     * Registers one or more named commands scoped to a context. Commands are
-     * the primary means for...
-     */
-    getCommandsModule() {
-        return {
-            defaultContext: 'VIEWER'
-            actions: { ... },
-            definitions: { ... }
-        }
-    },
-
-    /**
-     * Allows you to provide toolbar definitions that will be merged with any
-     * existing application toolbar configuration. Used to determine which
-     * buttons should be visible when, their order, what happens when they're
-     * clicked, etc.
-     */
-    getToolbarModule() {
-        return {
-            definitions: [ ... ],
-            defaultContext: 'ACTIVE_VIEWPORT::CORNERSTONE'
-        }
-    }
-
-    /**
-     * Not yet implemented
-     */
-    getPanelModule: () => null,
-
-    /**
-     * Registers a ReactComponent that should be used to render data in a
-     * Viewport. The first registered viewport is our "default viewport". If
-     * more than one viewport is registered, we use `SopClassHandlers` to
-     * determine which viewport should be used.
-    */
-    getViewportModule: () => reactViewportComponent,
-
-    /** Provides a whitelist of SOPClassUIDs the viewport is capable of rendering.
-     *  Can modify default behavior for methods like `getDisplaySetFromSeries` */
-    getSopClassHandler: () => {
-        id: 'some-other-unique-id',
-        sopClassUids: [ ... ],
-        getDisplaySetFromSeries: (series, study, dicomWebClient, authorizationHeaders) => { ... }
-    },
-}
-```
-
-### Modules
-
-There are a few different module types. Each module type allows us to extend the
-viewer in a different way, and provides a consistent API for us to do so. You
-can find a full list of the different types of modules
-[`in ohif-core`][module-types]. Information on each type of module, it's API,
-and how we determine when/where it should be used is included below.
-
-> NOTE: Modifying the extensions/modules registered to the OHIF Viewer currently
-> requires us to import and pass extensions to the ExtensionManager in
-> `src/App.js`, then rebuild the application. Long-term, we intend to make it
-> possible to accomplish this without a build step.
-
-#### Commands
-
-The Commands Module allows us to register one or more commands scoped to
-specific contexts. Commands can be run by [hotkeys][#], [toolbar buttons][#],
-and any registered custom react component (like a [viewport][#] or [panel][#]).
-Here is a simple example commands module:
-
-```js
-{
-    getCommandsModule() {

-#### Viewport
-
-An extension can register a Viewport Module by providing a `getViewportModule()`
-method that returns a React Component. The React component will receive the
-following props:
-
-```js
-children: PropTypes.arrayOf(PropTypes.element)
-studies: PropTypes.object,
-displaySet: PropTypes.object,
-viewportData: PropTypes.object, // { studies, displaySet }
-viewportIndex: PropTypes.number,
-children: PropTypes.node,
-customProps: PropTypes.object
-```
-
-Viewport components are managed by the `LayoutManager`. Which Viewport component
-is used depends on:
-
-- The Layout Configuration
-- Registered SopClassHandlers
-- The SopClassUID for visible/selected datasets
-

-
-#### Toolbar
-
-An extension can register a Toolbar Module by providing a `getToolbarModule()`
-method that returns a React Component. The component does not receive any props.
-If you want to modify or react to state, you will need to connect to the redux
-store.

-### Registering Extensions
-
-Extensions are registered for the application at startup. The
-`ExtensionManager`, exposed by `ohif-core`, registers a list of extensions with
-our application's store. Each module provided by the extension becomes available
-via `state.plugins.availablePlugins`, and consists of three parts: id, type
-([PLUGIN_TYPE](https://github.com/OHIF/ohif-core/blob/43c08a29eff3fb646a0e83a03a236ddd84f4a6e8/src/plugins.js#L1-L6)),
-and the return value of the module method.
-
-In a future version, we will likely expose a way to provide the extensions you
-would like included at startup.
-
-_app.js_
-
-```js
-import { createStore, combineReducers } from "redux";
-import OHIF from "@ohif/core";
-import OHIFCornerstoneExtension from "ohif-cornerstone-extension";
-
-const combined = combineReducers(OHIF.redux.reducers);
-const store = createStore(combined);
-const extensions = [new OHIFCornerstoneExtension()];
-
-// Dispatches the `addPlugin` action to the store
-// Adding extension modules to `state.plugins.availablePlugins`
-ExtensionManager.registerExtensions(store, extensions);
-```
-
-## OHIF Maintained Extensions
-
-A small number of powerful extensions for popular use cases are maintained by
-OHIF. They're co-located in the
-[`OHIF/Viewers`](https://github.com/OHIF/Viewers/tree/react/) repository, in the
-top level [`extensions/`](https://github.com/OHIF/Viewers/tree/react/extensions)

+# Architecture
+
+Looking to extend your instance of the OHIF Viewer? Want learn how to reuse _a
+portion_ of the Viewer in your own application? Or maybe you want to get
+involved and draft or suggest a new feature? Regardless, you're in the right
+place!
+
+The OHIF Viewer aims to be decoupled, configurable, and extensible; while this
+allows our code to be used in more ways, it also increases complexity. Below, we
+aim to demistify that complexity by providing insight into how our Viewer is
+architected, and the role each of it's dependent libraries plays.
+
+- [Overview](#overview)
+- [Business Logic](#business-logic)
+- [Component Library](#react-component-library)
+- [Extensions & Configuration](#extensions--configuration)
+- [Common Questions](#common-questions)
+
+## Overview
+
+The [OHIF Medical Image Viewing Platform][viewers-project] is maintained as a
+[`monorepo`][monorepo]. This means that this repository, instead of containing a
+single project, contains many projects. If you explore our project structure,
+you'll see the following:
+
+```bash
+.
+├── extensions
+│   ├── _example            # Skeleton of example extension
+│   ├── cornerstone         # 2D images w/ Cornerstone.js
+│   ├── dicom-html          # Structured Reports as HTML in viewport
+│   ├── dicom-microscopy    # Whole slide microscopy viewing
+│   ├── dicom-pdf           # View DICOM wrapped PDFs in viewport
+│   └── vtk                 # MPR and Volume support w/ VTK.js
+│
+├── platform
+│   ├── core                # Business Logic
+│   ├── i18n                # Internationalization Support
+│   ├── ui                  # React component library
+│   └── viewer              # Connects platform and extension projects
+│
+├── ...                     # misc. shared configuration
+├── lerna.json              # MonoRepo (Lerna) settings
+├── package.json            # Shared devDependencies and commands
+└── README.md
+```
+
+The `platform` directory contains the business logic library, component library,
+and the application library that combines them to create a powerful medical
+imaging viewer.
+
+The `extensions` directory contains many packages that can be registered with
+`@ohif/core`'s `ExtensionManager` to expand an application's supported features
+and functionality.
+
+![Architecture Diagram](../assets/img/architecture-diagram.png)
+
+<center><i>architecture diagram</i></center>
+
+This diagram is a conceptual illustration of how the Viewer is architected.
+
+1. (optional) `extensions` can be registered with `@ohif/core`'s
+   `ExtensionManager`
+2. `@ohif/core` provides bussiness logic and a way for `@ohif/viewer` to access
+   registered extensions
+3. The `@ohif/viewer` composes and provides data to components from our
+   component library (`@ohif/ui`)
+4. The `@ohif/viewer` can be built and served as a stand-alone PWA, or as an
+   embeddable package ([`@ohif/viewer`][viewer-npm])
+
+## Business Logic
+
+The [`@ohif/core`][core-github] project offers pre-packaged solutions for
+features common to Web-based medical imaging viewers. For example:
+
+- Hotkeys
+- DICOM Web requests
+- Hanging Protocols
+- Managing a study's measurements
+- Managing a study's DICOM metadata
+- [A flexible pattern for extensions](../extensions/index.md)
+- And many others
+
+It does this while remaining decoupled from any particular view library or
+rendering logic. While we use it to power our React Viewer, it can be used with
+Vue, React, Vanilla JS, or any number of other frameworks.
+
+## React Component Library
+
+[`@ohif/ui`][ui-github] is a React Component library that contains the reusable
+components that power the OHIF Viewer. It allows us to build, compose, and test
+components in isolation; easing the development process by reducing the need to
+stand-up a local PACS with test case data.
+
+Extension authors can also use these same components when building their
+extension's UI; allowing for a consistent look and feel with the rest of the
+application.
+
+[Check out our component library!](https://react.ohif.org/)
+
+## Extensions & Configuration
+
+While OHIF maintains several high value and commonly requested features in its
+own extensions, there are many instances where one may wish to further extend
+the viewer. Some common use cases include:
+
+- Adding AI/ML tools and insights
+- Custom workflows for guided diagnosis
+- Collecting specific annotations for training data or reports
+- Authentication and granular permissions
+- Teleconsultation workflow, image comments, and tracking
+- Adding surgical templating tools and reports
+- and many others
+
+We expose common integration points via [extensions](../extensions/index.md) to
+make this possible. The viewer and many of our own extensions also offer
+[configuration][configuration]. For a list of extensions maintained by OHIF,
+[check out this helpful table](../extensions/index.md#maintained-extensions).
+
+If you find yourself thinking "I wish the Viewer could do X", and you can't
+accomplish it with an extension today, create a GitHub issue! We're actively
+looking for ways to improve our extensibility ^\_^
+
+[Click here to read more about extensions!](../extensions/index.md)
+
+## Common Questions
+
+> When should I use the packaged source `@ohif/viewer` versus building a PWA
+> from the source?
+
+...
+
+> Can I create my own Viewer using Vue.js or Angular.js?
+
+You can, but you will not be able to leverage as much of the existing code and
+components. `@ohif/core` could still be used for business logic, and to provide
+a model for extensions. `@ohif/ui` would then become a guide for the components
+you would need to recreate.

+- [How do I configure my project?](#how-do-i-configure-my-project)
+
+## Overview
+
+### Configuration Files
+
+The configuration for our viewer is in the `<root>platform/viewer/public/config`
+directory. Our build process knows which configuration file to use based on the
+`APP_CONFIG` environment variable. By default, its value is
+[`config/default.js`][default-config]. The majority of the viewer's features,
+and registered extension's features, are configured using this file.
+
+**Embedded Use Note:**
+
+Alternatively, when using the `umd` bundle for embedded use cases, these same
+values are what you'll pass to `installViewer` method:
+
+`OHIFStandaloneViewer.installViewer(window.config)`
+
+### Environment Variables
+
+We use environment variables at build and dev time to change the Viewer's
+behavior. We can update the `HTML_TEMPLATE` to easily change which extensions
+are registered, and specify a different `APP_CONFIG` to connect to an
+alternative data source (or even specify different default hotkeys).
+
+| Environment Variable | Description                                                                                        | Default             |
+| -------------------- | -------------------------------------------------------------------------------------------------- | ------------------- |
+| `HTML_TEMPLATE`      | Which [HTML template][html-templates] to use as our web app's entry point. Specific to PWA builds. | `index.html`        |
+| `PUBLIC_URL`         | The route relative to the host that the app will be served from. Specific to PWA builds.           | `/`                 |
+| `APP_CONFIG`         | Which [configuration file][config-file] to copy to output as `app-config.js`                       | `config/default.js` |
+| `PROXY_TARGET`       | When developing, proxy requests that match this pattern to `PROXY_DOMAIN`                          | `undefined`         |
+| `PROXY_DOMAIN`       | When developing, proxy requests from `PROXY_TARGET` to `PROXY_DOMAIN`                              | `undefined`         |
+
+## How do I configure my project?
+
+The simplest way is to update the existing default config:
+
+_/platform/viewer/public/config/default.js_
+
+```js
+window.config = {
+  routerBasename: '/',
+  servers: {
+    dicomWeb: [
+      {
+        name: 'DCM4CHEE',
+        wadoUriRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/wado',
+        qidoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
+        wadoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
+        qidoSupportsIncludeField: true,
+        imageRendering: 'wadors',
+        thumbnailRendering: 'wadors',
+      },
+    ],
+  },
+};
+```
+
+The configuration can also be written as a JS Function in case you need to inject dependencies like external services:
+
+```js
+window.config = ({ servicesManager } = {}) => {
+  const { UIDialogService } = servicesManager.services;
+  return {
+    cornerstoneExtensionConfig: {
+      tools: {
+        ArrowAnnotate: {
+          configuration: {
+            getTextCallback: (callback, eventDetails) => UIDialogService.create({...
+          }
+        }
+      },
+    },
+    routerBasename: '/',
+    servers: {
+      dicomWeb: [
+        {
+          name: 'DCM4CHEE',
+          wadoUriRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/wado',
+          qidoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
+          wadoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
+          qidoSupportsIncludeField: true,
+          imageRendering: 'wadors',
+          thumbnailRendering: 'wadors',
+        },
+      ],
+    },
+  };
+};
+```
+
+You can also create a new config file and specify its path relative to the build
+output's root by setting the `APP_CONFIG` environment variable. You can set the
+value of this environment variable a few different ways:
+
+- ~[Add a temporary environment variable in your shell](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#adding-temporary-environment-variables-in-your-shell)~
+  - Previous `react-scripts` functionality that we need to duplicate with
+    `dotenv-webpack`
+- ~[Add environment specific variables in `.env` file(s)](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#adding-development-environment-variables-in-env)~
+  - Previous `react-scripts` functionality that we need to duplicate with
+    `dotenv-webpack`
+- Using the `cross-env` package in an npm script:
+  - `"build": "cross-env APP_CONFIG=config/my-config.js react-scripts build"`
+
+After updating the configuration, `yarn run build` to generate updated build
+output.

-# Contributing
-
-## I would like to contribute code - how do I do this?
-
-Fork the repository, make your change and submit a pull request.
-
-- The OHIF Viewer consists of code from three different repositories. Make sure
-  your change is modifying the appropriate one:
-  - `ohif-core`: Business Logic
-  - `react-viewerbase`: Reusable React Component Library
-  - `Viewers`: The glue, PWA, and primary extension point
-- At a minimum, you may want to read the following documentation:
-  - [Essentials: Getting Started](./essentials/getting-started.md)
-  - [Advanced: Architecture](./advanced/architecture.md)
-
-### When changes impact multiple repositories
-
-This is a particularly tricky scenario. We don't want to publish code in one
-repository, just so we can test and complete the other half of its requirements
-in another. Thankfully, there are a couple of ways you can test unpublished
-dependent changes locally before publishing:
-
-- [Use `yarn link`](https://yarnpkg.com/en/docs/cli/link)
-
-For example if you are working on `ohif-core` and would like to use your local
-version to debug a problem in `Viewers`, simply run yarn link inside of the
-`ohif-core` project.
-
-- If you're experiencing issues with `yarn link`,
-  [try `yalc`](https://github.com/whitecolor/yalc)
-
-Yalc provides an improved workflow as we add more and more dependent packages
-that are "in-progress". This comes into play as we begin working on extensions
-and their dependencies.
-
-```js
-// Install yalc for the first time
-yarn global add yalc
-
-// EXAMPLE: using an in-development version of ohif-core w/ Viewers locally
-// 1. Navigate to ohif-core's project root
-yarn install
-yalc publish
-
-// 2. Run the following after each change to ohif-core
-yarn build
-yalc push .
-
-// 3. Use the local package in our Viewers project. Navigate to the Viewers
-//    Project root.
-yarn install
-yalc add ohif-core
-yarn run dev
-```
-
-## Any guidance on submitting changes?
-
-While we do appreciate code contributions, triaging and integrating contributed
-code changes can be very time consuming. Please consider the following tips when
-working on your pull requests:
-
-- Functionality is appropriate for the repository. Consider creating a GitHub
-  issue to discuss your suggested changes.
-- The scope of the pull request is not too large. Please consider separate pull
-  requests for each feature as big pull requests are very time consuming to
-  understand.
-
-We will provide feedback on your pull requests as soon as possible. Following
-the tips above will help ensure your changes are reviewed.
-
-## Testing contribution pull requests
-
-OHIF uses [netlify](netlify.com) so that pull requests are autogenerated and
-available for testing.
-
-For example, [this url][example-url] allows you to test [pull request 237, the
-request that created this FAQ entry,][pr-237] using data pulled from Amazon S3.
-
-Replacing the number 237 in the link below with your pull request number should

 #### What if my archive doesn't support DicomWeb?
 
-> This is possible to do with the OHIF Viewer, but not as straightforward. Look

+It's possible to supply all Study data via JSON format, in the event you do not have a DicomWeb endpoint.
+You can host all of the relevant files on any web accessible server (Amazon S3, Azure Blob Storage, Local file server etc.)
+
+This JSON is supplied via the '?url=' query parameter.
+It should reference an endpoint that returns **application/json** formatted text.
+
+If you do not have an API, you can simply return a text file containing the JSON from any web server.
+
+
+You tell the OHIF viewer to use JSON by appending the `'?url='` query to the `/Viewer` route:
+
+eg. `https://my-test-ohif-server/viewer?url=https://my-json-server/study-uid.json`
+
+The returned JSON object must contain a single root object with a 'studies' array.

+More info on this JSON format can be found here [Issue #1500](https://github.com/OHIF/Viewers/issues/1500)
+
+
+**Implementation Notes:**
+
+1. When hosting the viewer, you will also need to host a /viewer route on the server - or the browser may not be able to find the route.
+2. For each instance url (dicom object) in the returned JSON, you must prefix the `url` with `dicomweb:` in order for the cornerstone image loader to retrieve it correctly.
+ eg. `https://image-server/my-image.dcm` ---> `dicomweb:https://image-server/my-image.dcm`
+3. The JSON format above is compatible with >= v3.7.8 of the application. Older versions of the viewer used a different JSON format. As of 20/04/20 the public [https://viewer.ohif.org/] is a pre 3.0 version that does not support this format yet.
+4. The JSON format is case-sensitive. Please ensure you have matched casing with the naturalised Dicom format referenced in [Issue #1500](https://github.com/OHIF/Viewers/issues/1500).
+
+*CORS Issues (Cross-Origin Resource Sharing)*
+
+If you host a JSON API or Images on a different domain from the the app itself, you will likely have CORS issues. This will also happen when testing from Localhost and reaching out to remote servers.
+Even if the domain is the same, different ports, subdomains or protocols (https vs http) will also cause CORS errors.
+You will to need add a configuration on each server hosting these assets to allow your App server origin.
+
+For example:
+
+Lets assume your application is hosted on `https://my-ohif-server.com`.
+
+Your JSON API is hosted on `https://my-json-api.aws.com`
+
+And your images are stored on Amazon S3 at `https://my-s3-bucket.aws.com`
+
+When you first start your application, browsing to `https://my-ohif-server.com/viewer?url=https://my-json-api.aws.com/api/my-json-study-info.json`, you will likely get a CORS error in the browser console as it tries to connect to `https://my-json-api.aws.com`.
+
+Adding a setting on the JSON server to allow the CORS origin = `https://my-ohif-server.com` should solve this.
+
+Next, you will likely get a similar CORS error, as the browser tries to go to `https://my-s3-bucket.aws.com`.
+You will need to go to the S3 bucket configuration, and add a CORS setting to allow origin = `https://my-ohif-server.com`.
+
+Essentially, whenever the application connects to a remote resource, you will need to add the applications url to the allowed CORS Origins on that resource. Adding an origin similar to https://localhost:3000 will also allow for local testing.

 ### Configuration
 
-> This step assumes you have an imaging archive. If you need assistance setting
-> one up, check out the [`Data Source` Guide](./../../essentials/data-source.md)
-> or a deployment recipe that contains an open source Image Archive
+The configuration for our viewer is in the `<root>platform/viewer/public/config`
+directory. Our build process knows which configuration file to use based on the
+`APP_CONFIG` environment variable. By default, its value is
+[`config/default.js`][default-config]. The majority of the viewer's features,
+and registered extension's features, are configured using this file.
 
-#### How it Works
-
-The configuration for our project is in the `/public/config` directory. Our
-build process knows which configuration file to use based on the
-`REACT_APP_CONFIG` environment variable. By default, its value is
-[`default.js`](https://github.com/OHIF/Viewers/blob/react/public/config/default.js).
-When we build, the `%REACT_APP_CONFIG%` value in
-our[`/public/index.html`](https://github.com/OHIF/Viewers/blob/react/public/index.html#L12-L15)
-file is substituted for the correct configuration file's name. This sets
-the`window.config` equal to our configuration file's value.
-
-#### How do I configure my project?
-
-The simplest way is to update the existing default config:
-
-_/public/config/default.js_
-
-```js
-window.config = {
-  routerBasename: '/',
-  servers: {
-    dicomWeb: [
-      {
-        name: 'DCM4CHEE',
-        wadoUriRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/wado',
-        qidoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
-        wadoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',

-          requestFromBrowser: true,
-        },
-      },
-    ],
-  },
-}
-```
-
-You can also create a new config file and specify its path relative to the build
-output's root by setting the `REACT_APP_CONFIG` environment variable. You can
-set the value of this environment variable a few different ways:
-
-- [Add a temporary environment variable in your shell](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#adding-temporary-environment-variables-in-your-shell)
-- [Add environment specific variables in `.env` file(s)](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#adding-development-environment-variables-in-env)
-- Using the `cross-env` package in an npm script:
-  - `"build": "cross-env REACT_APP_CONFIG=config/my-config.js react-scripts build"`
-
-After updating the configuration, `yarn run build:web` to generate updated build
-output.
+The easiest way to apply your own configuration is to modify the `default.js`
+file. For more advanced cofiguration options, check out our

-#### Tips & Tricks
+You can see a live example of this recipe in [this CodeSandbox][code-sandbox].
+
+## Add Extensions
+
+The UMD build of the OHIF Viewer is a "light weight" build that only contains
+the core extensions required for basic 2D image viewing. It's possible to add
+other extensions at runtime.
+
+This only requires us to include a single script tag, and add it using the
+`extensions` key to our config. In this practical example, we register our
+popular whole slide microscopy extension:
+
+```html
+<script
+  src="https://unpkg.com/@ohif/extension-dicom-microscopy@0.50.5/dist/index.umd.js"
+  crossorigin
+></script>
+
+<!-- --->
+<script>
+  window.config = {
+    // ...
+    extensions: [OHIFExtDicomMicroscopy],
+  };
+</script>
+```
+
+You can see an example of a slide microscopy study in the viewer [with the
+extension enabled here][whole-slide-ext-demo] ([source code][ext-code-sandbox])
+and [without it here][whole-slide-base-demo] ([source code][code-sandbox]).
+
+You can read more about extensions and how to create your own in our
+[extensions guide](/extensions/index.md).

+> We're trying to embed the OHIF Viewer into an existing React App, but seeing

+
+If you are installing OHIF viewer inside another react app, you may use `installViewer` as follows:

+import { installViewer } from '@ohif/viewer'
+
+const ohifViewerConfig = window.config // or set it here
+const containerId = 'ohif'
+const componentRenderedOrUpdatedCallback = function() {

+    );
+}
+
+render () {
+   ...
+   //you can render in any element you wish
+   <AnyTag id={containerId}/>
+}
+
+```
+
+`installViewer` is a convenience method that pulls in some dependencies that may
+not be compatible with existing `react` apps. `@ohif/viewer` also exports `App`
+which is a react component that takes the `configuration` outlined above as
+props. You can use it as a reusable component, and to avoid `react` version

+in the root `.netlify` directory.
+
+## Workflows
+
+[CircleCI Workflows][circleci-workflows] are a set of rules for defining a
+collection of jobs and their run order. They are self-documenting and their
+configuration can be found in our CircleCI configuration file:
+`.circleci/config.yml`.
+
+### Workflow: PR_CHECKS
+
+The PR_CHECKS workflow (Pull Request Checks) runs our automated unit and
+end-to-end tests for every code check-in. These tests must all pass before code
+can be merged to our `master` branch.

+  </a>
+  <div><i>Workflow diagram for PR_CHECKS</i></div>
+</div>
+
+### Workflow: PR_OPTIONAL_DOCKER_PUBLISH
+
+The PR_OPTIONAL_DOCKER_PUBLISH workflow allows for "manual approval" to publish
+the pull request as a tagged docker image. This is helpful when changes need to
+be tested with the Google Adapter before merging to `master`.

+
+> NOTE: This workflow will fail unless it's for a branch on our `upstream`
+> repository. If you need this functionality, but the branch is from a fork,
+> merge the changes to a short-lived `feature/` branch on `upstream`
+
+### Workflow: DEPLOY
+
+The DEPLOY workflow deploys the OHIF Viewer when changes are merged to master.
+It uses the Netlify CLI to deploy assets created as part of the repository's PWA
+Build process (`yarn run build`). The workflow allows for "Manual Approval" to
+promote the build to `STAGING` and `PRODUCTION` environments.

+
+### Workflow: RELEASE
+
+The RELEASE workflow publishes our `npm` packages, updated documentation, and
+`docker` image when changes are merged to master. `Lerna` and "Semantic Commit
+Syntax" are used to independently version and publish the many packages in our
+monorepository. If a new version is cut/released, a Docker image is created.
+Documentation is generated with `gitbook` and pushed to our `gh-pages` branch.
+GitHub hosts the `gh-pages` branch with GitHub Pages.

+# Contributing
+
+## How can I help?
+
+Fork the repository, make your change and submit a pull request. If you would
+like to discuss the changes you intend to make to clarify where or how they
+should be implemented, please don't hesitate to create a new issue. At a
+minimum, you may want to read the following documentation:
+
+- [Getting Started](/development/getting-started.md)
+- [Architecture](/architecture/index.md)
+
+Pull requests that are:
+
+- Small
+- [Well tested](./testing.md)
+- Decoupled
+
+Are much more likely to get reviewed and merged in a timely manner.
+
+## When changes impact multiple repositories
+
+While this can be tricky, we've tried to reduce how often this situation crops
+up this with our [recent switch to a monorepo][monorepo]. Our maintained
+extensions, ui components, internationalization library, and business logic can
+all be developed by simply running `yarn run dev` from the repository root.
+
+Testing the viewer with locally developed, unpublished package changes from a
+package outside of the monorepo is most common with extension development. Let's
+demonstrate how to accomplish this with two commonly forked extension
+dependencies:
+
+### `cornerstone-tools`
+
+On your local file system:
+
+```bash
+# code/my-projects/
+.
+├── cornerstonejs/cornerstone-tools
+└── ohif/viewers
+```
+
+- Open a terminal/shell
+- Navigate to `cornerstonejs/cornerstone-tools`
+  - `npm install`
+  - [`yarn link`](https://yarnpkg.com/en/docs/cli/link)
+  - `npm run dev`
+- Open a new terminal/shell
+- Navigate to `ohif/viewers`.
+  - `yarn install`
+  - [`yarn link cornerstone-tools`](https://yarnpkg.com/en/docs/cli/link)
+  - `yarn run dev`
+
+As you make changed to `cornerstone-tools`, and it's output is rebuilt, you
+should see the following behavior:
+
+<div style="text-align: center;">
+  <a href="/assets/img/cornerstone-tools-link.gif">
+    <img src="/assets/img/cornerstone-tools-link.gif" alt="Example of linked cornerstone-tools package" style="margin: 0 auto; max-width: 500px;" />
+  </a>
+  <div><i>example of linked cornerstone-tools package</i></div>
+</div>
+
+If you wish to stop using your local package, run the following commands in the
+`ohif/viewers` repository root:
+
+- `yarn unlink cornerstone-tools`
+- `yarn install --force`
+
+### `react-vtkjs-viewport`
+
+On your local file system:
+
+```bash
+# code/my-projects/
+.
+├── ohif/react-vtkjs-viewport
+└── ohif/viewers
+```
+
+- Open a terminal/shell
+- Navigate to `ohif/react-vtkjs-viewport`
+  - `yarn install`
+  - [`yarn link`](https://yarnpkg.com/en/docs/cli/link)
+  - `yarn run start`
+- Open a new terminal/shell
+- Navigate to `ohif/viewers`.
+  - `yarn install`
+  - [`yarn link react-vtkjs-viewport`](https://yarnpkg.com/en/docs/cli/link)
+  - `yarn run dev`
+
+#### Other linkage notes
+
+We're still working out some of the kinks with local package development as
+there are a lot of factors that can influence the behavior of our development
+server and bundler. If you encounter issues not addressed here, please don't
+hesitate to reach out on GitHub.
+
+## Any guidance on submitting changes?
+
+While we do appreciate code contributions, triaging and integrating contributed
+code changes can be very time consuming. Please consider the following tips when
+working on your pull requests:
+
+- Functionality is appropriate for the repository. Consider creating a GitHub
+  issue to discuss your suggested changes.
+- The scope of the pull request is not too large. Please consider separate pull
+  requests for each feature as big pull requests are very time consuming to
+  understand.
+
+We will provide feedback on your pull requests as soon as possible. Following
+the tips above will help ensure your changes are reviewed.
+
+## Testing contribution pull requests
+
+OHIF uses [netlify](https://www.netlify.com/) so that pull requests are
+autogenerated and available for testing.
+
+For example, [this url][example-url] allows you to test [pull request 237, the
+request that created this FAQ entry,][pr-237] using data pulled from Amazon S3.
+
+Replacing the number 237 in the link below with your pull request number should
+let you test it as well and you can use this link for discussions on github
+without requiring reviewers to download and build your branch.
+
+```bash
+https://deploy-preview-237--ohif.netlify.com/viewer/?url=https://s3.eu-central-1.amazonaws.com/ohif-viewer/sampleDICOM.json
+```
+
+If you have made a documentation change, a link like this will let you preview
+the gitbook generated by the pull request:
+
+```bash
+https://deploy-preview-237--ohif.netlify.com/contributing.html
+```

+# Contributing: Tests
+
+> Testing is an opinionated topic. Here is a rough overview of our testing
+> philosiphy. See something you want to discuss or think should be changed? Open
+> a PR and let's discuss.
+
+You're an engineer. You know how to write code, and writing tests isn't all that
+different. But do you know why we write tests? Do you know when to write one, or
+what kind of test to write? How do you know if a test is a _"good"_ test? This
+document's goal is to give you the tools you need to make those determinations.
+
+Okay. So why do we write tests? To increase our... **CONFIDENCE**
+
+- If I do a large refactor, does everything still work?
+- If I changed some critical piece of code, is it safe to push to production?
+
+Gaining the confidence we need to answer these questions after every change is
+costly. Good tests allow us to answer them without manual regression testing.
+What and how we choose to test to increase that confidence is nuanced.
+
+## Kinds of Tests
+
+Test's buy us confidence, but not all tests are created equal. Each kind of test
+has a different cost to write and maintain. An expensive test is worth it if it
+gives us confidence that a payment is processed, but it may not be the best
+choice for asserting an element's border color.
+
+| Test Type   | Example                                                                  | Speed            | Cost                                                                     |
+| ----------- | ------------------------------------------------------------------------ | ---------------- | ------------------------------------------------------------------------ |
+| Static      | `addNums(1, '2')` called with `string`, expected `int`.                  | :rocket: Instant | :money_with_wings:                                                       |
+| Unit        | `addNums(1, 2)` returns expected result `3`                              | :airplane: Fast  | :money_with_wings::money_with_wings:                                     |
+| Integration | Clicking "Sign In", navigates to the dashboard (mocked network requests) | :running: Okay   | :money_with_wings::money_with_wings::money_with_wings:                   |
+| End-to-end  | Clicking "Sign In", navigates to the dashboard (no mocks)                | :turtle: Slow    | :money_with_wings::money_with_wings::money_with_wings::money_with_wings: |
+
+- :rocket: Speed: How quickly tests run
+- :money_with_wings: Cost: Time to write, and to debug when broken (more points
+  of failure)
+
+### Static Code Analysis
+
+Modern tooling gives us this "for free". It can catch invalid regular
+expressions, unused variables, and guarantee we're calling methods/functions
+with the expected paramater types.
+
+Example Tooling:
+
+- [ESLint][eslint-rules]
+- [TypeScript][typescript-docs] or [Flow][flow-org]
+
+### Unit Tests
+
+The building blocks of our libraries and applications. For these, you'll often
+be testing a single function or method. Conceptually, this equates to:
+
+_Pure Function Test:_
+
+- If I call `sum(2, 2)`, I expect the output to be `4`
+
+_Side Effect Test:_
+
+- If I call `resetViewport(viewport)`, I expect `cornerstone.reset` to be called
+  with `viewport`
+
+#### When to use
+
+Anything that is exposed as public API should have unit tests.
+
+#### When to avoid
+
+You're actually testing implementation details. You're testing implementation
+details if:
+
+- Your test does something that the consumer of your code would never do.
+  - IE. Using a private function
+- A refactor can break your tests
+
+### Integration Tests
+
+We write integration tests to gain confidence that several units work together.
+Generally, we want to mock as little as possible for these tests. In practice,
+this means only mocking network requests.
+
+#### When to use
+
+...
+
+### End-to-End Tests
+
+These are the most expensive tests to write and maintain. Largely because, when
+they fail, they have the largest number of potential points of failure. So why
+do we write them? Because they also buy us the most confidence.
+
+#### When to use
+
+Mission critical features and functionality, or to cover a large breadth of
+functionality until unit tests catch up. Unsure if we should have a test for
+feature `X` or scenario `Y`? Open an issue and let's discuss.
+
+## Summary
+
+- Does your test increase confidence?
+- Does the test type chosen balance the cost-to-confidence ratio?

-# Configuration
-
-> This step assumes you have an imaging archive. If you need assistance setting
-> one up, check out the [`Data Source` Guide](./data-source.md) or a deployment
-> recipe that contains an open source Image Archive
-
-## How it Works
-
-The configuration for our project is in the `/public/config` directory. Our
-build process knows which configuration file to use based on the
-`REACT_APP_CONFIG` environment variable. By default, its value is
-[`default.js`](https://github.com/OHIF/Viewers/blob/react/public/config/default.js).
-When we build, the `%REACT_APP_CONFIG%` value in
-our[`/public/index.html`](https://github.com/OHIF/Viewers/blob/react/public/index.html#L12-L15)
-file is substituted for the correct configuration file's name. This sets the
-`window.config` equal to our configuration file's value.
-
-## How do I configure my project?
-
-The simplest way is to update the existing default config:
-
-_/public/config/default.js_
-
-```js
-window.config = {
-  routerBasename: '/',
-  servers: {
-    dicomWeb: [
-      {
-        name: 'DCM4CHEE',
-        wadoUriRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/wado',
-        qidoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
-        wadoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs',
-        qidoSupportsIncludeField: true,
-        imageRendering: 'wadors',
-        thumbnailRendering: 'wadors',
-        requestOptions: {
-          requestFromBrowser: true,
-        },
-      },
-    ],
-  },
-}
-```
-
-You can also create a new config file and specify its path relative to the build
-output's root by setting the `REACT_APP_CONFIG` environment variable. You can
-set the value of this environment variable a few different ways:
-
-- [Add a temporary environment variable in your shell](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#adding-temporary-environment-variables-in-your-shell)
-- [Add environment specific variables in `.env` file(s)](https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables#adding-development-environment-variables-in-env)
-- Using the `cross-env` package in an npm script:
-  - `"build": "cross-env REACT_APP_CONFIG=config/my-config.js react-scripts build"`
-
-After updating the configuration, `yarn run build:web` to generate updated build
-output.

-# Installation
-
-It's important to know that the OHIF Viewer project provides two different build
-processes:
-
-```bash
-# Static Asset output: For deploying PWAs
-yarn run build:web
-
-# Single `.js` script, for embedding viewer into existing apps
-yarn run build:package
-```
-
-## create-react-app (PWA)
-
-> [create-react-app](https://github.com/facebook/create-react-app) provides
-> pre-configured build process for developing front-end applications with
-> [React](https://reactjs.org/).
-
-The ohif-viewer package can be run as a create-react-app application. This is
-useful for development, debugging, or evolving the OHIF Viewer into your own
-custom imaging application.
-
-You can read more about this particular strategy in our
-[Build for Production Deployment Guide](./../deployment/recipes/build-for-production.md)
-
-## Rollup (Packaged Script)
-
-> [Rollup](https://rollupjs.org/guide/en) is a module bundler for JavaScript. It
-> uses the new standardized format for code modules included in the ES6 revision
-> of JavaScript.
-
-The [ohif-viewer](https://www.npmjs.com/package/ohif-viewer) package can be
-built with Rollup to provide a set of React components which can be dropped into
-a larger application. Specifically, the ohif-viewer package provides a React
-component named `OHIFViewer` which is the entire viewer, configurable via React
-`props`. This is useful for including the OHIF Viewer in a larger web
-application, as the entire application can be provided via a `<script>` tag with
-no build process required.

-## Debugging Steps
-
-### Can't retrieve Study List over DICOMWeb
-
-1. Check that you can query your PACS using an alternative DICOM Web client
-   (e.g. cURL, or a Web Browser). If you cannot, then your PACS is configured
-   incorrectly. Refer to the documentation of the image archive.

+
+## Overview
+
+We use extensions to help us isolate and package groups of related features.
+Extensions provide functionality, ui components, and new behaviors. Ideally,
+they're built in a way that allows them to extend entirely different
+implementations of the `@ohif/viewer` project.
+
+<div style="text-align: center;">
+  <a href="/assets/img/extensions-diagram.png">
+    <img src="/assets/img/extensions-diagram.png" alt="Extensions Diagram" style="margin: 0 auto; max-width: 500px;" />
+  </a>
+  <div><i>Diagram showing how extensions are configured and accessed.</i></div>
+</div>
+
+The `@ohif/viewer`'s application level configuration gives us the ability to add
+and configure extensions. When the application starts, extensions are registered
+with the `ExtensionManager`. Different portions of the `@ohif/viewer` project
+will use registered extensions to influence application behavior.
+
+Extensions allow us to:
+
+- Wrap and integrate functionality of 3rd party dependencies in a reusable way
+- Change how application data is mapped and transformed
+- Display a consistent/cohesive UI
+- Inject custom components to override built-in components
+
+Practical examples of extensions include:
+
+- A set of segmentation tools that build on top of the `cornerstone` viewport
+- Showing ML/AI report summaries for the selected study/series/image
+- Support for parsing DICOM structured reports and displaying them in a user
+  friendly way
+- [See our maintained extensions for more examples of what's possible](#maintained-extensions)
+
+## Concepts
+
+### Extension Skeleton
+
+An extension is a plain JavaScript object that has an `id` property, and one or
+more [modules](#modules) and/or [lifecycle hooks](#lifecycle-hooks).
+
+```js
+// prettier-ignore
+export default {
+  /**
+   * Only required property. Should be a unique value across all extensions.
+   */
+  id: 'example-extension',
+
+  // Lifecyle
+  preRegistration() { /* */ },
+  // Modules
+  getCommandsModule() { /* */ },
+  getToolbarModule() { /* */ },
+  getPanelModule() { /* */ },
+  getSopClassHandler() { /* */ },
+  getViewportModule() { /* */ },
+}
+```
+
+### Registering an Extension
+
+There are two different ways to register and configure extensions: At
+[runtime](#registering-at-runtime) and at
+[build time](#registering-at-build-time).
+
+You can leverage one or both strategies. Which one(s) you choose depend on your
+application's requirements. Each [module](#modules) defined by the extension
+becomes available to the core application via the `ExtensionManager`.
+
+#### Registering at Runtime
+
+The `@ohif/viewer` uses a [configuration file](../viewer/configuration.md) at
+startup. The schema for that file includes an `Extensions` key that supports an
+array of extensions to register.
+
+```js
+// prettier-ignore
+const config = {
+  extensions: [
+    MyFirstExtension,
+    [
+      MySecondExtension,
+      { /* MySecondExtensions Configuration */ },
+    ],
+  ];
+}
+```
+
+#### Registering at Build Time
+
+The `@ohif/viewer` works best when built as a "Progressive Web Application"
+(PWA). If you know the extensions your application will need, you can specify
+them at "build time" to leverage advantages afforded to us by modern tooling:
+
+- Code Splitting (dynamic imports)
+- Tree Shaking
+- Dependency deduplication
+
+You can update the list of bundled extensions by:
+
+1. Having your `@ohif/viewer` project depend on the extension
+2. Importing and adding it to the list of extensions in the
+   `<repo-root>/platform/src/index.js` entrypoint.
+
+### Lifecycle Hooks
+
+Currently, there is only a single lifecycle hook for extensions:
+[`preRegistration`](./lifecycle/pre-registration.md)
+
+If an extension defines the [`preRegistration`](./lifecycle/pre-registration.md)
+lifecycle hook, it is called before any modules are registered in the
+`ExtensionManager`. It's most commonly used to wire up extensions to
+[services](./../services/index.md) and [commands](./modules/commands.md), and to
+bootstrap 3rd party libraries.
+
+### Modules
+
+Modules are the meat of extensions. They provide "definitions", components, and
+filtering/mapping logic that are then made available by various managers and
+services.
+
+Each module type has a special purpose, and is consumed by our viewer
+differently.
+
+| Type                                              | Description                                                      | Examples                                          |
+| ------------------------------------------------- | ---------------------------------------------------------------- | ------------------------------------------------- |
+| [Commands](./modules/commands.md)                 | Adds named commands, scoped to a context, to the CommandsManager | `setToolActive()`, `nextSeries()`                 |
+| [Panel](./modules/panel.md)                       | Adds left or right hand side panels                              | `<ThumbnailList />`, `<MeasurementsTable />`      |
+| [SOPClassHandler](./modules/sop-class-handler.md) | Determines how retrieved study data is split into "DisplaySets"  | `getDisplaySetFromSeries()`                       |
+| [Toolbar](./modules/toolbar.md)                   | Adds buttons or custom components to the toolbar                 | Toolbar button, nested buttons, custom            |
+| [Viewport](./modules/viewport.md)                 | Adds a component responsible for rendering a "DisplaySet"        | `<CornerstoneViewport />`, `<DicomPdfViewport />` |
+
+<figure style="text-align: center; font-style: italic;">Tbl. Module types with abridged descriptions and examples. Each module links to a dedicated documentation page.</figure>
+
+### Contexts
+
+The `@ohif/viewer` tracks "active contexts" that extensions can use to scope
+their functionality. Some example contexts being:
+
+- Route: `ROUTE:VIEWER`, `ROUTE:STUDY_LIST`
+- Active Viewport: `ACTIVE_VIEWPORT:CORNERSTONE`, `ACTIVE_VIEWPORT:VTK`
+
+An extension module can use these to say "Only show this Toolbar Button if the
+active viewport is a Cornerstone viewport." This helps us use the appropriate UI
+and behaviors depending on the current contexts.
+
+For example, if we have hotkey that "rotates the active viewport", each Viewport
+module that supports this behavior can add a command with the same name, scoped
+to the appropriate context. When the `command` is fired, the "active contexts"
+are used to determine the appropriate implementation of the rotate behavior.
+
+## Consuming Extensions
+
+We consume extensions, via the `ExtensionManager`, in our `@ohif/viewer`
+project.
+
+```js
+const extensionManager = new ExtensionManager({
+  commandsManager,
+  servicesManager,
+});
+
+// prettier-ignore
+extensionManager.registerExtensions([ /** **/ ]);
+```
+
+The `@ohif/viewer` project handles data fetching, basic routing, wires up UI
+services, and is the home to the more bespoke application logic that doesn't
+make as much sense to make reusable.
+
+Long-term, replacing the `@ohif/viewer` application and consuming extensions
+(and the `ExtensionManager`) in your own project is the ideal path for
+applications requiring a high degree of customization that can't be achieved
+with current theming, configuration, extension, and services support.
+
+If you're not sure how to achieve your goals with the extensibility available
+today, create a GitHub issue!
+
+### `ExtensionManager`
+
+The `ExtensionManager` is a class made available to us via the `@ohif/core`
+project (platform/core). Our application instantiates a single instance of it,
+and provides a `ServicesManager` and `CommandsManager` along with the
+application's configuration through the appConfig key (optional).
+
+```js
+const commandsManager = new CommandsManager();
+const servicesManager = new ServicesManager();
+const extensionManager = new ExtensionManager({
+  commandsManager,
+  servicesManager,
+  appConfig,
+});
+```
+
+The `ExtensionManager` only has a few public members:
+
+- `registerExtension` - Registers a single extension
+- `registerExtensions` - Registers an array of extensions
+- `modules` - An object containing registered extensions by `MODULE_TYPE`
+
+During registration, lifecycle hooks and modules have access to the extension's
+config, the application's config and `ExtensionManager`'s `ServicesManager` and
+`CommandsManager` instances.
+
+Our `@ohif/viewer` uses the `modules` member to access registered extensions at
+appropriate places in our application.
+
+## Maintained Extensions
+
+A small number of powerful extensions for popular use cases are maintained by
+OHIF. They're co-located in the [`OHIF/Viewers`][viewers-repo] repository, in
+the top level [`extensions/`][ext-source] directory.

+# Lifecylce Hook: preRegistration
+
+If an extension defines the `preRegistration` lifecycle hook, it is called
+before any modules are registered in the `ExtensionManager`. This hook can be
+used to:

+- initialize 3rd party libraries
+- register event listeners
+- add or call services

+  - [Public API](#public-api)
+  - [Contexts](#contexts)
+
+## Overview
+
+An extension can register a Commands Module by defining a `getCommandsModule`
+method. The Commands Module allows us to register one or more commands scoped to
+specific [contexts](./../index.md#contexts). Commands have several unique
+characteristics that make them tremendously powerful:
+
+- Multiple implementations for the same command can be defined
+- Only the correct command's implementation will be run, dependent on the
+  application's "context"
+- Commands can be called from extensions, modules, and the consuming application
+
+Here is a simple example commands module:
+
+```js
+export default {
+  id: 'example-commands-module',
+
+  /**
+   * @param {object} params
+   * @param {ServicesManager} params.servicesManager
+   * @param {CommandsManager} params.commandsManager
+   */
+  getCommandsModule({ servicesManager, commandsManager }) {
+    return {
+      definitions: {
+        sayHello: {
+          commandFn: ({ words }) => {
+            console.log(words);
+          },
+          options: { words: 'Hello!' },
+        },
+      },
+      defaultContext: 'VIEWER',
+    };
+  },
+};
+```
+
+Each definition returned by the Commands Module is registered to the
+`ExtensionManager`'s `CommandsManager`.
+
+## Command Definitions
+
+The command definition consists of a named command (`myCommandName` below) and a
+`commandFn`. The command name is used to call the command, and the `commandFn`
+is the "command" that is actioned.
+
+```js
+myCommandName: {
+	commandFn: ({ viewports, other, options }) => { },
+	storeContexts: ['viewports'],
+	options: { words: 'Just kidding! Goodbye!' },
+	context: 'ACTIVE_VIEWPORT::CORNERSTONE',
+}
+```
+
+| Property        | Type               | Description                                                                                                                             |
+| --------------- | ------------------ | --------------------------------------------------------------------------------------------------------------------------------------- |
+| `commandFn`     | func               | The function to call when command is run. Receives `options` and `storeContexts`.                                                       |
+| `storeContexts` | string[]           | (optional) Expected state objects to be passed in as props. Located using `getAppState` fn defined at `CommandsManager`'s instatiation. |
+| `options`       | object             | (optional) Arguments to pass at the time of calling to the `commandFn`                                                                  |
+| `context`       | string[] or string | (optional) Overrides the `defaultContext`. Let's us know if command is currently "available" to be run.                                 |
+
+## Command Behavior
+
+**I have many similar commands. How can I share their `commandFn` and make it
+reusable?**
+
+This is where `storeContexts` and `options` come in. We use these in our
+`setToolActive` command. `storeContexts` helps us identify our `activeViewport`,
+and `options` allow us to pass in the name of a tool we would like to set as
+active.
+
+**If there are multiple valid commands for the application's active contexts**
+
+- What happens: all commands are run
+- When to use: A `clearData` command that cleans up state for multiple
+  extensions
+
+**If no commands are valid for the application's active contexts**
+
+- What happens: a warning is printed to the console
+- When to use: a `hotkey` (like "invert") that doesn't make sense for the
+  current viewport (PDF or HTML)
+
+## `CommandsManager`
+
+The `CommandsManager` is a class defined in the `@ohif/core` project. A single
+instance of it should be defined in the consuming application, and it should be
+used when constructing the `ExtensionManager`.
+
+### Instantiating
+
+When we instantiate the `CommandsManager`, we need to pass it two methods:
+
+- `getAppState` - Should return the application's state when called
+- `getActiveContexts` - Should return the application's active contexts when
+  called
+
+These methods are used internally to help determine which commands are currently
+valid, and how to provide them with any state they may need at the time they are
+called.
+
+```js
+const commandsManager = new CommandsManager({
+  getAppState,
+  getActiveContexts,
+});
+```
+
+### Public API
+
+If you would like to run a command in the consuming app or an extension, you can
+use one of the following methods:
+
+```js
+// Returns all commands for a given context
+commandsManager.getContext('string');
+
+// Attempts to run a command
+commandsManager.runCommand('speak', { command: 'hello' });
+
+// Run command, but override the active contexts
+commandsManager.runCommand('speak', { command: 'hello' }, ['VIEWER']);
+```
+
+The `ExtensionManager` handles registering commands and creating contexts, so
+most consumer's won't need these methods. If you find yourself using these, ask
+yourself "why can't I register these commands via an extension?"
+
+```js
+// Used by the `ExtensionManager` to register new commands
+commandsManager.registerCommand('context', 'name', commandDefinition);
+
+// Creates a new context; clears the context if it already exists
+commandsManager.createContext('string');
+```
+
+### Contexts
+
+It is up to the consuming application to define what contexts are possible, and
+which ones are currently active. As extensions depend heavily on these, we will
+likely publish guidance around creating contexts, and ways to override extension
+defined contexts in the near future. If you would like to discuss potential
+changes to how contexts work, please don't hesistate to createa new GitHub
+issue.
+
+[Some additional information on Contexts can be found here.](./../index.md#contexts)

+# Module: Panel
+
+An extension can register a Panel Module by defining a `getPanelModule` method.

+# Module: SOP Class Handler
+
+An extension can register a [SOP Class][sop-class-link] Handler Module by
+defining a `getSopClassHandlerModule` method. The [SOP Class][sop-class-link]
+Handler is a bit different from the other modules, as it doesn't provide a `1:1`
+schema for UI or provide it's own components. It instead defines:
+
+- `sopClassUIDs`: an array of string SOP Class UIDs that the
+  `getDisplaySetFromSeries` method should be applied to.
+- `getDisplaySetFromSeries`: a method that maps series and study metadata to a
+  display set
+
+A `displaySet` has the following shape:
+
+```js
+return {
+  plugin: 'html',
+  Modality: 'SR',
+  displaySetInstanceUID: 0,
+  wadoRoot: study.getData().wadoRoot,
+  wadoUri: instance.getData().wadouri,
+  SOPInstanceUID: instance.getSOPInstanceUID(),
+  SeriesInstanceUID: series.getSeriesInstanceUID(),
+  StudyInstanceUID: study.getStudyInstanceUID(),
+  authorizationHeaders,
+};
+```
+
+Where the `plugin` key is used to influence the default `ViewportComponent` for
+rendering the `displaySet`. Additional properties are passed to the
+`ViewportComponent` and used by the default `StudyBrowser` to render
+"thumbnails" for each `displaySet`
+
+## Example SOP Class Handler Module
+
+```js
+const SOP_CLASS_UIDS = {
+  BASIC_TEXT_SR: '1.2.840.10008.5.1.4.1.1.88.11',
+  ENHANCED_SR: '1.2.840.10008.5.1.4.1.1.88.22',
+};
+
+export default {
+  id: 'example-sop-class-handler-module',
+
+/**
+ * @param {object} params
+ * @param {ServicesManager} params.servicesManager
+ * @param {CommandsManager} params.commandsManager
+ */
+getSopClassHandlerModule({ servicesManager, commandsManager }) {
+  return {
+    id: 'OHIFDicomHtmlSopClassHandler',
+    sopClassUIDs: Object.values(SOP_CLASS_UIDS),
+
+    /**
+     * @param {object} series -
+     * @param {object} study -
+     * @param {object} dicomWebClient -
+     * @param {object} authorizationHeaders -
+     */
+    getDisplaySetFromSeries(series, study, dicomWebClient, authorizationHeaders) {
+      const instance = series.getFirstInstance();
+
+      return {
+        plugin: 'html',
+        displaySetInstanceUID: 0,
+        wadoRoot: study.getData().wadoRoot,
+        wadoUri: instance.getData().wadouri,
+        SOPInstanceUID: instance.getSOPInstanceUID(),
+        SeriesInstanceUID: series.getSeriesInstanceUID(),
+        StudyInstanceUID: study.getStudyInstanceUID(),
+        authorizationHeaders,
+      };
+    },
+  }
+};
+```
+
+### More examples :
+
+- [Dicom-HTML SOP][dicom-html-sop]
+- [Dicom-PDF SOP][dicom-pdf-sop]
+- [Dicom-Microscopy SOP][dicom-micro-sop]
+- [Dicom-Segmentation SOP][dicom-seg-sop]
+
+## `@ohif/viewer` usage
+
+We use the `sopClassHandlerModule`s in three different places:
+
+- `ViewerLocalFileData.js`
+- `ViewerRetrieveStudyData.js`
+- `StandaloneRouting.js`
+
+Each time, it is used to map study and series data to `displaySets`. It does
+this by working alongside the `StudyMetadataManager` in `@ohif/core`. That
+manager has the method `createDisplaySets` that takes an array of
+`sopClassHandlerModules`.

+# Module: Toolbar
+
+An extension can register a Toolbar Module by defining a `getToolbarModule`
+method. This module is commonly used to define:
+
+- [Toolbar buttons](#button-definitions)
+- [Nested toolbar menus](#nested-toolbar-menus)
+- [Custom components](#custom-components)
+
+![Toolbar Extension](../../assets/img/extensions-toolbar.gif)
+
+<center><i>Example toolbar button using the Dialog Service to show CINE controls.</i></center>
+
+## Example Toolbar Module
+
+The Toolbar Module should return an array of `definitions` and a
+`defaultContext`. There are currently a few different variations of definitions,
+each one is detailed further down.
+
+```js
+export default {
+  id: 'example-toolbar-module',
+
+  /**
+   * @param {object} params
+   * @param {ServicesManager} params.servicesManager
+   * @param {CommandsManager} params.commandsManager
+   */
+  getToolbarModule({ servicesManager, commandsManager }) {
+    return {
+      definitions: [
+        /* Array of definitions */
+      ],
+      defaultContext: ['ROUTE:VIEWER'],
+    };
+  },
+};
+```
+
+## Button Definitions
+
+The simplest definition has the following properties:
+
+```js
+{
+  id: 'StackScroll',
+  label: 'Stack Scroll',
+  icon: 'bars',
+  type: 'setToolActive',
+  commandName: 'setToolActive',
+  commandOptions: { toolName: 'StackScroll' },
+},
+```
+
+| property         | description                                                       | values                                    |
+| ---------------- | ----------------------------------------------------------------- | ----------------------------------------- |
+| `id`             | Unique string identifier for the definition                       | \*                                        |
+| `label`          | User/display friendly to show in UI                               | \*                                        |
+| `icon`           | A string name for an icon supported by the consuming application. | \*                                        |
+| `type`           | Used to determine the button's component and behavior             | `"setToolActive"`, `"command"`            |
+| `commandName`    | (optional) The command to run when the button is used.            | Any command registed by a `CommandModule` |
+| `commandOptions` | (optional) Options to pass the target `commandName`               | \*                                        |
+| `context`        | (optional) Overrides module's `defaultContext`                    | Array of string context names             |
+
+Where a button with a `type` of `setToolActive` has an "active" styling applied
+when clicked; removing the active styling from all other buttons.
+
+## Nested Toolbar Menus
+
+You can indicate that buttons should be grouped and nested in a submenu by
+including `buttons` property in a definition:
+
+```js
+{
+  id: 'More',
+  label: 'More',
+  icon: 'ellipse-circle',
+  buttons: [
+    {
+      id: 'cstInvert',
+      label: 'Invert',
+      icon: 'circle',
+      type: 'command',
+      commandName: 'invertViewport',
+    },
+  ],
+},
+```
+
+![Toolbar Extension](../../assets/img/extensions-toolbar-nested.gif)
+
+<center><i>Example toolbar button demonstrating nested buttons.</i></center>
+
+## Custom Components
+
+The Toolbar Modules supports rendering custom components in place of the
+application's default. In place of the `type`, `commandName`, and
+`commandOptions` properties, we instead specify a `CustomComponent`.
+
+```js
+{
+  id: 'Custom',
+  label: 'Custom',
+  icon: 'custom-icon',
+  CustomComponent: CustomToolbarComponent,
+}
+
+```
+
+The `CustomComponent` components will receive the following props:
+
+```html
+<CustomComponent
+  parentContext="{parentContext}"
+  toolbarClickCallback="{_handleToolbarButtonClick.bind(this)}"
+  button="{button}"
+  key="{button.id}"
+  activeButtons="{activeButtonsIds}"
+  isActive="{isActive}"
+/>
+```
+
+| Property               | Type     | Description                     |
+| ---------------------- | -------- | ------------------------------- |
+| `activeButtons`        | string[] | list of active buttons          |
+| `button`               | object   | its own definition object       |
+| `key`                  | string   | React key prop                  |
+| `isActive`             | boolean  | If current button is active     |
+| `parentContext`        | ?        | The parent component's context? |
+| `toolbarClickCallback` | func     | Callback method for clicks      |

+# Module: Viewport
+
+An extension can register a Viewport Module by defining a `getViewportModule`
+method that returns a React component. Currently, we use viewport components to
+add support for:
+
+- 2D Medical Image Viewing (cornerstone ext.)
+- Structured Reports as HTML (dicom html ext.)
+- Encapsulated PDFs as PDFs (dicom pdf ext.)
+- Whole Slide Microscopy Viewing (whole slide ext.)
+- etc.
+
+The general pattern is, the [`sopClassHandlerModule`](#) helps us determine
+which Viewport Component a set of `sopClassUIDs` should default to. The Viewport
+Component receives props containing a display set it should know how to render.
+
+## Viewport Component Props
+
+Each `ViewportComponent` will receive the following props:
+
+```html
+<viewportComponent
+  viewportData="{viewportData}"
+  viewportIndex="{viewportIndex}"
+  children="{[children]}"
+/>
+```
+
+| Property        | Type            | Description                       |
+| --------------- | --------------- | --------------------------------- |
+| `children`      | React.element[] |                                   |
+| `viewportData`  | object          | `viewportSpecificData` (probably) |
+| `viewportIndex` | number          |                                   |
+
+### `@ohif/viewer`
+
+Viewport components are managed by the `ViewportGrid` Component. Which Viewport
+component is used depends on:
+
+- The Layout Configuration
+- Registered SopClassHandlers
+- The SopClassUID for visible/selected datasets

+# Browser Support
+
+The browsers that we support are specified in the `.browserlistrc` file located
+in the `platform/viewer` project. While we leverage the latest language features
+when writing code, we rely on `babel` to _transpile_ our code so that it can run
+in the browsers that we support.
+
+## In Practice
+
+The OHIF Viewer is capable of _running_ on:
+
+- IE 11
+- FireFox
+- Chrome
+- Safari
+- Edge
+
+However, we do not have the resources to adequately test and maintain bug free
+functionality across all of these. In order to push web based medical imaging
+forward, we focus our development efforts on recent version of modern evergreen
+browsers.
+
+Our support of older browsers equates to our willingness to review PRs for bug
+fixes, and target their minimum JS support whenever possible.
+
+### Polyfills
+
+> A polyfill, or polyfiller, is a piece of code (or plugin) that provides the
+> technology that you, the developer, expect the browser to provide natively.
+
+An example of a polyfill is that you expect `Array.prototype.filter` to exist,
+but for some reason, the browser that's being used has not implemented that
+language feature yet. Our earlier transpilation will rectify _syntax_
+discrepencies, but unimplemented features require a "temporary" implementation.
+That's where polyfills step in.
+
+You can utilize a service like [polyfill.io](https://polyfill.io/v3/) to
+auto-detect and apply polyfills as needed, or you can update the PWA build to
+include polyfill's in your bundle by incorporating [core-js][core-js]

+# PWA vs Packaged
+
+It's important to know that the OHIF Viewer project provides two different build
+processes:
+
+```bash
+# Static Asset output: For deploying PWAs
+yarn run build
+
+# Single `.js` script, for embedding viewer into existing apps
+yarn run build:package
+```
+
+## Progressive Web Application (PWA)
+
+> [Progressive Web Apps][pwa] are a new breed of web applications that meet the
+> [following requirements][pwa-checklist]. Notably, targeting a PWA allows us
+> provide a reliable, fast, and engaging experience across different devices and
+> network conditions.
+
+The OHIF Viewer is maintained as a [monorepo][monorepo]. We use WebPack to build
+the many small static assets that comprise our application. Also generated is an
+`index.html` that will serve as an entry point for loading configuration and the
+application, as well as a `service-worker` that can intelligently cache files so
+that subsequent requests are from the local file system instead of over the
+network.
+
+You can read more about this particular strategy in our
+[Build for Production Deployment Guide](./../deployment/recipes/build-for-production.md)
+
+## Commonjs Bundle (Packaged Script)
+
+The [@ohif/viewer][viewer-npm] package is built with WebPack to provide a React
+component that can be dropped into a larger application. The `OHIFViewer`
+component is the entire viewer, configurable via React `props`. This is useful
+for including the OHIF Viewer in a larger web application, as the entire
+application can be provided via a `<script>` tag with no build process required.
+
+The bundle is not as performant or as optimized as the PWA build. It includes
+fonts, styles, and the core extensions. If you find yourself facing performance
+issues, you may wish to tweak what's included in this bundle or switch to the
+PWA build.

-Emailing developers directly is not a shortcut to faster support. Please file
-your issues and questions on Github so that everyone can benefit from the
-discussion and solutions.
-
-### Do your Viewers have [510(k) Clearance][501k-clearance] from the U.S. F.D.A or [CE Marking][ce-marking] from the European Commission?
-
-**NO.** The OHIF Viewer, Lesion Tracker, and Standalone Viewer, **NOT** F.D.A.
-cleared or CE Marked. It is the users responsibility to ensure compliance with
-applicable rules and regulations. The
-[License](https://github.com/OHIF/Viewers/blob/master/LICENSE) for the OHIF
-Framework does not prevent your company or group from seeking F.D.A. clearance
-for a product built using the framework.
-
-If you have gone this route (or are going there), please let us know because we
-would be interested to hear about your experience.
-
-### Are your Viewers [HIPAA][hipaa] Compliant?
-
-**NO.** The OHIF Viewer, Lesion Tracker, and Standalone Viewer **DO NOT**
-fulfill all of the criteria to become HIPAA Compliant. It is the users
-responsibility to ensure compliance with applicable rules and regulations.

+# Our Process
+
+Our process is a living, breathing thing. We strive to have regular
+[retrospectives][retrospective] that help us shape and adapt our process to our
+team's current needs. This document attempts to capture the broad strokes of
+that process in an effort to:
+
+- Strengthen community member involvement and understanding
+- Welcome feedback and helpful suggestions
+
+## Overview
+
+- [Issue Triage](#issue-triage)
+- [Issue Curation ("backlog grooming")](#issue-curation-backlog-grooming)
+- [Contributions (Pull Requests)](#contributions-pull-requests)
+- [Releases](#releases)

+_Include issue lifecycle diagram_
+
+## Issue Triage
+
+[GitHub issues][gh-issues] are the best way to provide feedback, ask questions,
+and suggest changes to the OHIF Viewer's core team. Community issues generally
+fall into one of three categories, and are marked with a `triage` label when
+created.
+
+| Issue Template Name    | Description                                                                              |
+| ---------------------- | ---------------------------------------------------------------------------------------- |
+| Community: Report 🐛   | Describe a new issue; Provide steps to reproduce; Expected versus actual result?         |
+| Community: Request ✋  | Describe a proposed new feature. Why should it be implemented? What is the impact/value? |
+| Community: Question ❓ | Seek clarification or assistance relevant to the repository.                             |
+
+_table 1. issue template names and descriptions_
+
+Issues that require `triage` are akin to support tickets. As this is often our
+first contact with would-be adopters and contributors, it's important that we
+strive for timely responses and satisfactory resolutions. We attempt to
+accomplish this by:
+
+1. Responding to issues requiring `triage` at least once a week
+2. Create new "official issues" from "community issues"
+3. Provide clear guidance and next steps (when applicable)
+4. Regularly clean up old (stale) issues
+
+> :pencil: Less obviously, patterns in the issues being reported can highlight
+> areas that need improvement. For example, users often have difficulty
+> navigating CORS issues when deploying the OHIF Viewer -- how do we best reduce
+> our ticket volume for this issue?
+
+### Backlogged Issues
+
+Community issues serve as vehicles of discussion that lead us to "backlogged
+issues". Backlogged issues are the distilled and actionable information
+extracted from community issues. They contain the scope and requirements
+necessary for hand-off to a core-team (or community) contributor ^\_^
+

+_table 2. backlogged issue types ([full list of labels][gh-labels])_
+
+## Issue Curation (["backlog grooming"][groom-backlog])
+
+If a [GitHub issue][gh-issues] has a `bug`, `story`, or `task` label; it's on
+our backlog. If an issue is on our backlog, it means we are, at the very least,
+committed to reviewing any community drafted Pull Requests to complete the
+issue. If you're interested in seeing an issue completed but don't know where to
+start, please don't hesitate to leave a comment!
+
+While we don't yet have a long-term or quarterly road map, we do regularly add
+items to our ["Active Development" GitHub Project Board][gh-board]. Items on
+this project board are either in active development by Core Team members, or
+queued up for development as in-progress items are completed.

+
+## Contributions (Pull Requests)
+
+Incoming Pull Requests (PRs) are triaged using the following labels. Code review
+is performed on all PRs where the bug fix or added functionality is deemed
+appropriate:
+
+| Labels                                         | Description                                                                                                 |

+| [PR: Bug Fix][label-bug]                       | Filed to address a Bug.                                                                                     |
+| [PR: Draft][draft]                             | Filed to gather early feedback from the core team, but which is not intended for merging in the short term. |
+| **Review Workflow**                            |                                                                                                             |
+| [PR: Awaiting Response 💬][awaiting-response]  | The core team is waiting for additional information from the author.                                        |
+| [PR: Awaiting Review 👀][awaiting-review]      | The core team has not yet performed a code review.                                                          |
+| [PR: Awaiting Revisions 🖊][awaiting-revisions] | Following code review, this label is applied until the author has made sufficient changes.                  |
+| **QA**                                         |                                                                                                             |
+| [PR: Awaiting User Cases 💃][awaiting-stories] | The PR code changes need common language descriptions of impact to end users before the review can start    |
+| [PR: No UX Impact 🙃][no-ux-impact]            | The PR code changes do not impact the user's experience                                                     |
+
+We rely on GitHub Checks and integrations with third party services to evaluate
+changes in code quality and test coverage. Tests must pass and User cases must
+be present (when applicable) before a PR can be merged to master, and code
+quality and test coverage must not changed by a significant margin. For some
+repositories, visual screenshot-based tests are also included, and video
+recordings of end-to-end tests are stored for later review.
+
+[You can read more about our continous integration efforts here](/development/continous-integration.md)
+
+## Releases
+
+Releases are made automatically based on the type of commits which have been
+merged (major.minor.patch). Releases are automatically pushed to NPM. Release
+notes are automatically generated. Users can subscribe to GitHub and NPM
+releases.
+
+We host development, staging, and production environments for the Progressive
+Web Application version of the OHIF Viewer. [Development][ohif-dev] always
+reflects the latest changes on our master branch. [Staging][ohif-stage] is used
+to regression test a release before a bi-weekly deploy to our [Production
+environment][ohif-prod].
+
+Important announcements are made on GitHub, tagged as Announcement, and pinned
+so that they remain at the top of the Issue page.
+
+The Core team occasionally performs full manual testing to begin the process of
+releasing a Stable version. Once testing is complete, the known issues are
+addressed and a Stable version is released.

+## Options
+
+### 1. Pre-built PWA
+
+...
+
+### 2. Script-Tag
+
+...
+
+### 3. Docker
+
+...
+
+## Security Concerns
+
+- Secure your data
+
+## Common Issues
+
+- Missing server rewrite rules
