+Keystone Event Notifications
+============================
+
+Keystone provides notifications about usage data so that 3rd party applications
+can use the data for billing, monitoring, or quota purposes.  This document
+describes the current inclusions and exclusions for Keystone usage
+notifications.
+
+
+Create/Delete/Update User
+=========================
+
+One notification is sent when a user
+is successfully created, deleted, or updated.
+
+The following message is sent when create user finishes::
+
+ {"event_type": "identity.user.created",
+  "message_id": "<message ID>",
+  "publisher_id": "identity.<hostname>",
+  "timestamp": "<timestamp>",
+  "priority": "INFO",
+  "payload":
+   {"resource_info": "<resource ID>"}}
+
+Notifications for deletes and updates are similar to those for creates, with
+``deleted`` or ``updated`` replacing ``created`` in the above notification.
+
+If the operation fails, the notification won't be sent, and no special
+error notification will be sent.  Information about the error is handled
+through normal exception paths.
+
+
+Notification Example
+====================
+
+This is an example of a notification sent for user creation::
+
+ {"event_type": "identity.user.created",
+  "message_id": "0156ee79-b35f-4cef-ac37-d4a85f231c69",
+  "publisher_id": "identity.host1234",
+  "timestamp": "2013-08-29 19:03:45.960280",
+  "priority": "INFO",
+  "payload":
+   {"resource_info": "671da331c47d4e29bb6ea1d270154ec3"}}
