+Integration with edx-platform
+******************************
+
+This repository became an edx-platform's dependency starting with the Ulmo release. From that release onwards, system policies are automatically updated.
+
+If you need to update the policies manually, it is recommended to use the ``./manage.py lms load_policies`` command.
+
+.. note::
+    Currently, this package only supports the `content libraries' roles and permissions as documented here`_, and the migration of data from the old system to the new one is performed automatically.
+
+    If you need to migrate the information manually, you should run ``./manage.py lms migrate openedx_authz``.
+
