 NOTE: The OAuth2 Client in Keycloak must be given the `view-users` _Service Account Role_ for the realm that the users are in.
 
+The user-info-fetcher requires a service account in Keycloak with the permissions to read user objects.
+To create such as user you need to take the following steps:
+
+*With your user realm selected* click on `Clients` at the left side and use the `Import client` button:

+The HTTP API exposed by the user-info-fetcher can be called directly using the rego function `http.send`.
+However, we provide a convenience rego rule library, which we ship with `OpaClusters` by default.

 For example, the following rule allows access for users in the `/admin` group:
