+# EVENT BUS
+# Below are Django settings related to setting up the Open edX event bus.
+# Because the event bus requires a Docker based networking layer, as included in devstack, the event bus does not work
+# outside of a Docker container. Therefore, the settings related to networking are set to None, because this file is
+# used for the local application server. However, because these local Django settings are also used by Tutor, we include
+# sensible values for non-network related settings. Tutor users can override these settings when setting up the event
+# bus, including the network-related settings.
