+# REST Identity store
+The REST backend allows you to query identity data in existing webapps, like:
+- Forums (phpBB, Discourse, etc.)
+- Custom Identity stores (Keycloak, ...)
+- CRMs (Wordpress, ...)
+- self-hosted clouds (Nextcloud, ownCloud, ...)
+
+To integrate this backend with your webapp, you will need to implement three specific REST endpoints detailed below.
+
+## Features
+|      Name      | Supported? |
+|----------------|------------|
+| Authentication | Yes        |
+| Directory      | Yes        |
+| Identity       | Yes        |
+
+## Configuration
+| Key                              | Default                                        | Description                                          |
+|----------------------------------|------------------------------------------------|------------------------------------------------------|
+| `rest.enabled`                   | `false`                                        | Globally enable/disable the REST backend             |
+| `rest.host`                      | *None*                                        | Default base URL to use for the different endpoints. |
+| `rest.endpoints.auth`            | `/_mxisd/backend/api/v1/auth/login`            | Validate credentials and get user profile            |
+| `rest.endpoints.directory`       | `/_mxisd/backend/api/v1/directory/user/search` | Search for users by arbitrary input                  |
+| `rest.endpoints.identity.single` | `/_mxisd/backend/api/v1/identity/single`       | Endpoint to query a single 3PID                      |
+| `rest.endpoints.identity.bulk`   | `/_mxisd/backend/api/v1/identity/bulk`         | Endpoint to query a list of 3PID                     |
+
+Endpoint values can handle two formats:
+- URL Path starting with `/` that gets happened to the `rest.host`
+- Full URL, if you want each endpoint to go to a specific server/protocol/port
+
+`rest.host` is mandatory if at least one endpoint is not a full URL.
+
