 #### What if my archive doesn't support DicomWeb?
 
-> This is possible to do with the OHIF Viewer, but not as straightforward. Look
-> out for documentation on this subject in the near future.
+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.

 > 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 () {

+   <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
 conflict issues.

+ *  A hierarchical list of UIDs is a regular JS Array where the type of the UID
+ *  (study, series, instance) is determined by its nasting lavel. For example:
+ *    @ The following list instructs the library to download all the instances
+ *      from both studies "A" and "B":
+ *
+ *    ['studyUIDFromA', 'studyUIDFromB']
+ *
+ *    @ In the previous example both UIDs are treated as STUDY UIDs because both
+ *      of them are listed in the same (top) level of the list. If, on the other
+ *      hand, only instances from series "I" and "J" from the study "B"
+ *      are to be downloaded, the expected hierarchical list would be:
+ *
+ *    ['studyUIDFromA', ['studyUIDFromB', ['seriesUIDFromI', 'seriesUIDFromJ']]]
+ *
+ *    @ Which, when prettified, reads like this:
+ *
+ *    [
+ *      'studyUIDFromA',
+ *      ['studyUIDFromB', [
+ *        'seriesUIDFromI',
+ *        'seriesUIDFromJ'
+ *      ]]
+ *    ]
+ *
+ *    @ Furthermore, if only instances "X", "Y" and "Z" from series "J" need to
+ *      be downloaded (instead of all the instances from that series), the list
+ *      could be changed to:
+ *
+ *    [
+ *      'studyUIDFromA',

+ *        ]]
+ *      ]]
+ *    ]
+ *
+ * Please refer to hierarchicalListUtils.js for more information and utilities;

+ * @param {function} options.progress A callback to retrieve notifications
+ * @returns {Promise} A promise that resolves to an URL from which the ZIP file

+   * updated after the structs are loaded) that React its not aware of its changes
+   * because the module object its not passed in to the panel component as prop but accessed externally.
+   *
+   * Improving this event approach to something reactive that can be tracked inside the react lifecycle,
+   * allows us to easily watch the module or the rtstruct loading process in any other component
