 #### 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.
-> out for documentation on this subject in the near future.
+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.
