+# 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
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+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
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at danny.ri.brown+OHIFcoc@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-> ATTENTION: If you are looking for Version 1 (the Meteor Version) of this
-> repository, it lives on
-> [the `v1.x` branch](https://github.com/OHIF/Viewers/tree/v1.x)
+## About

-## Why?
+The OHIF Medical Imaging Viewer is for viewing medical images. It can retrieve
+and load images from most sources and formats; render sets in 2D, 3D, and
+reconstructed representations; allows for the manipulation, annotation, and
+serialization of observations; supports internationalization, OpenID Connect,
+offline use, hotkeys, and many more features.

-Building a web based medical imaging viewer from scratch is time intensive, hard
-to get right, and expensive. Instead of re-inventing the wheel, you can use the
-OHIF Viewer as a rock solid platform to build on top of. The Viewer is a
-[React][react-url] [Progressive Web Application][pwa-url] that can be embedded
-in existing applications via it's [packaged source
-(ohif-viewer)][ohif-viewer-url] or hosted stand-alone. The Viewer exposes
-[configuration][configuration-url] and [extensions][extensions-url] to support
-workflow customization and advanced functionality at common integration points.
+Almost everything offers some degree of customization and configuration. If it
+doesn't support something you need, we accept pull requests and have an ever
+improving Extension System.

-If you're interested in using the OHIF Viewer, but you're not sure it supports
-your use case [check out our docs](https://docs.ohif.org/). Still not sure, or
-you would like to propose new features? Don't hesitate to
-[create an issue](https://github.com/OHIF/Viewers/issues) or open a pull
-request.
+## Why Choose Us

-## Getting Started
+### Community & Experience

-This readme is specific to testing and developing locally. If you're more
-interested in production deployment strategies,
-[you can check out our documentation on publishing](https://docs.ohif.org/).
+The OHIF Viewer is a collaborative effort that has served as the basis for many
+active, production, and FDA Cleared medical imaging viewers. It benefits from
+our extensive community's collective experience, and from the sponsored
+contributions of individuals, research groups, and commercial organizations.

-Want to play around before you dig in?
-[Check out our LIVE Demo](https://viewer.ohif.org/)
+### Built to Adapt

-### Setup
+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:

-_Requirements:_
+- 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

- [NodeJS & NPM](https://nodejs.org/en/download/)
- [Yarn](https://yarnpkg.com/lang/en/docs/install/)
+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).

-_Steps:_
+### Support

+## Quick Start Deployment

-### Developing Locally
+> This is only one of many ways to configure and deploy the OHIF Viewer. To
+> learn more about your options, and how to choose the best one for your
+> requirements, check out
+> [our deployment recipes and documentation](https://docs.ohif.org/deployment/).

-In your cloned repository's root folder, run:
+The fastest and easiest way to get started is to include the OHIF Viewer with a
+script tag. In practice, this is as simple as:
+
+- Including the following dependencies with script tags:
+  - [React](https://unpkg.com/react@16/umd/react.production.min.js)
+  - [React Dom](https://unpkg.com/react-dom@16/umd/react-dom.production.min.js)
+  - The [OHIF Viewer](https://unpkg.com/@ohif/viewer)
+- Have an element with an ID of `root` on the page
+- Configure the OHIF Viewer at `window.config`:

 ```js
-// Restore dependencies
+window.config = {
+  routerBasename: '/',
+  servers: {
+    dicomWeb: [
+      {
+        name: 'DCM4CHEE',
+        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',
+      },
+    ],
+  },
+};
+```
+
+- Install the viewer:
+  `window.OHIFStandaloneViewer.installViewer(window.config);`
+
+This exact setup is demonstrated in this
+[CodeSandbox](https://codesandbox.io/s/viewer-script-tag-tprch) and in our
+[Embedding The Viewer](https://docs.ohif.org/deployment/recipes/embedded-viewer.html)
+deployment recipe.

-It is notoriously difficult to setup multiple dependent repositories for
-end-to-end testing and development. That's why we recommend writing and running
-unit tests when adding and modifying features. This allows us to program in
-isolation without a complex setup, and has the added benefit of producing
-well-tested business logic.
+\* - For more information on our different builds, check out our [Deploy
+Docs][deployment-docs]

-1. Clone this repository
-2. Navigate to the project directory, and `yarn install`
-3. To begin making changes, `yarn run dev`
-4. To commit changes, run `yarn run cm`
+## Projects

-When creating tests, place the test file "next to" the file you're testing.
-[For example](https://github.com/OHIF/Viewers/blob/master/src/utils/index.test.js):
+The OHIF Medical Image Viewing Platform 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:

-# 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`](https://github.com/OHIF/Viewers/tree/react) repository
-contains the source code for the OHIF Medical Imaging Viewer. It is effectively
-a React
-[progressive web app](https://developers.google.com/web/progressive-web-apps/)
-(PWA) that combines the business logic housed in
-[`OHIF/ohif-core`](https://github.com/OHIF/ohif-core) and the components in our
-React Component library
-[`OHIF/react-viewerbase`](https://github.com/OHIF/react-viewerbase). It provides
-customization for common use cases through
-[configuration](../essentials/configuration.md) and for adding functionality via
-[extensions](./extensions.md).
-
-### 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 ^\_^

-## 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.

-# Tool Management
-
-This is not yet exposed in an easy/convenient way. Most tools are currently
-added by creating new Viewport, Toolbar, and SOPInstanceHandler extension
-modules. You can read more about that approach in [extensions](./extensions.md).
-
-In the near future, we intend to improve the extensibility of tools for existing
-Viewports (like our Cornerstone.js and VTK.js viewports).
@@ -1,113 +0,0 @@
-# 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 class or object that has a `getExtensionId()` method, and one or more "module" methods. You can find an abbreviated extension below, or [view the source](https://github.com/OHIF/Viewers/blob/react/extensions/ohif-cornerstone-extension/src/OHIFCornerstoneExtension.js#L32-L65) of our `cornerstone` viewport extension.
-
-```js
-class myCustomExtension {
-
-    /** Required */
-    getExtensionId: () => 'my-extension-id';
-
-    /** React component that receives props from ConnectLayoutManager
-     *  If more than one viewport module is registered, SopClassHandler
-     *  is used to help determine which component is used */
-    getViewportModule: () => reactViewportComponent;
-
-    /** React component that adds buttons/behavior to the viewer Toolbar */
-    getToolbarModule: () => reactToolbarComponent;
-
-    /** 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',
-        type: PLUGIN_TYPES.SOP_CLASS_HANDLER,
-        sopClassUids: ['string'],
-        getDisplaySetFromSeries: (series, study, dicomWebClient, authorizationHeaders) => ...
-    };
-
-    // Not yet used
-    getPanelModule: () => null;
-}
-```
-
-### Modules
-
-There are a few different kinds of modules. Each kind of module 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`](https://github.com/OHIF/ohif-core/blob/43c08a29eff3fb646a0e83a03a236ddd84f4a6e8/src/plugins.js#L1-L6). Information on each type of module, it's API, and how we determine when/where it should be used is included below:
-
-#### 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
-
-![Cornerstone Viewport](../assets/img/extensions-viewport.png)
-
-<center><i>An example of three Viewports</i></center>
-
-For a complete example implementation, [check out the OHIFCornerstoneViewport](https://github.com/OHIF/Viewers/blob/react/extensions/ohif-cornerstone-extension/src/OHIFCornerstoneViewport.js).
-
-#### 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.
-
-![Toolbar Extension](../assets/img/extensions-toolbar.gif)
-
-<center><i>A toolbar extension example</i></center>
-
-Toolbar components are rendered in the `ToolbarRow` component.
-
-For a complete example implementation, [check out the OHIFCornerstoneViewport's Toolbar Module](https://github.com/OHIF/Viewers/blob/react/extensions/ohif-cornerstone-extension/src/ToolbarModule.js).
-
-#### SopClassHandler
-
-...
-
-#### Panel
-
-> The panel module is not yet in use.
-
-### 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) directory.

+## 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

+└── 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.

+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.

+
+## 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.mdl#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 ^\_^

+
+## 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.

 Let's take a look at what's going on under the hood here. `yarn run dev:orthanc`
 is running the `dev:orthanc` script in our project's `package.json`. That script
 is:

 ```js
-cross-env PORT=5000 REACT_APP_CONFIG=config/docker_nginx-orthanc.js react-scripts start

+
+## 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

-> 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: '/',
-  relativeWebWorkerScriptsPath: '',
-  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.
+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).

+# Continous Integration (CI)
+
+This repository uses `CircleCI` and `Netlify` for continous integration.
+
+## Deploy Previews
+
+[Netlify Deploy previews][deploy-previews] are generated for every pull request.
+They allow pull request authors and reviewers to "Preview" the OHIF Viewer as if
+the changes had been merged.
+
+Deploy previews can be configured by modifying the `netlify.toml` file in the
+root of the repository. Some additional scripts/assets for netlify are included
+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.

+
+## 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">

+  </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`

+- 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](netlify.com) so that pull requests are autogenerated and

+# 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: '/',
-  relativeWebWorkerScriptsPath: '',
-  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.

-
-# Single `.js` script, for embedding viewer into existing apps
-yarn run build:package

-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

-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.

+
+## 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](#runtime-extensions) and at [build time](#bundled-extensions).
+
+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](#) 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
+- add or call commands
+
+The `preRegistration` hook receives an object containing the
+`ExtensionManager`'s associated `ServicesManager`, `CommandsManager`, and any
+`configuration` that was provided with the extension at time of registration.
+
+_Example `preRegistration` hook implementation_

+# Module: Commands

+  - [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)
