+
+Enabling the configurator
+=========================
+
+Because the configurator is under continue development and it might change over time, it is disabled by default in TLJH.
+If you want to experiment with it, it can be enabled using ``tljh-config``:
+
+.. code-block:: bash
+
+    sudo tljh-config set services.configurator.enabled True
+    sudo tljh-config reload
+
+Accessing the Configurator
+==========================
+
+After enabling the configurator using ``tljh-config``, the service will only be available to hub admins, from within the control panel.
+The configurator can be accessed from under ``Services`` in the top navigation bar. It will ask to authenticate, so it knows the user is an admin.
+Once done, the configurator interface will be available.
