+Configure Nova Notifications
+============================
+
+Watcher can consume notifications generated by the Nova services, in order to
+build or update, in real time, its cluster data model related to computing
+resources.
+
+Nova publishes, by default, notifications on ``notifications`` AMQP queue
+(configurable) and ``versioned_notifications`` AMQP queue (not
+configurable). ``notifications`` queue is mainly used by ceilometer, so we can
+not use it. And some events, related to nova-compute service state, are only
+sent into the ``versioned_notifications`` queue.
+
+By default, Watcher listens to AMQP queues named ``watcher_notifications``
+and ``versioned_notifications``. So you have to update the Nova
+configuration file on controller and compute nodes, in order
+to Watcher receives Nova notifications in ``watcher_notifications`` as well.
+
+  * In the file ``/etc/nova/nova.conf``, update the section
+    ``[oslo_messaging_notifications]``, by redefining the list of topics
+    into which Nova services will publish events ::
+
+      [oslo_messaging_notifications]
+      driver = messaging
+      topics = notifications,watcher_notifications
+
+  * Restart the Nova services.
