 Authentication is required and the user must be an admin.
 
+Configuration options:
+ 
+* `[:auth, :enforce_oauth_admin_scope_usage]` — OAuth admin scope requirement toggle.
+    If `true`, admin actions explicitly demand admin OAuth scope(s) presence in OAuth token (client app must support admin scopes).
+    If `false` and token doesn't have admin scope(s), `is_admin` user flag grants access to admin-specific actions.
+    Note that client app needs to explicitly support admin scopes and request them when obtaining auth token.
