     XEP-0030: Service Discovery
 
+    Service discovery in XMPP allows entities to discover information about
+    other agents in the network, such as the feature sets supported by a
+    client, or signposts to other, related entities.
+
+    Also see <http://www.xmpp.org/extensions/xep-0030.html>.
+
+    The XEP-0030 plugin works using a hierarchy of dynamic
+    node handlers, ranging from global handlers to specific
+    JID+node handlers. The default set of handlers operate
+    in a static manner, storing disco information in memory.
+    However, custom handlers may use any available backend
+    storage mechanism desired, such as SQLite or Redis.
