 Exposes server information over Pub/Sub per ProtoXEP: PubSub Server Information.
 
-This initial version only announces support (used to 'opt-in', per the XEP). It does not publish any data. This is intended to be a future addition to this mod.
+This version, announces support (used to 'opt-in', per the XEP) and publishes the name of the local domain via a Pub/Sub node. The published data
+will contain an unnamed 'remote-domain' element for each inbound or outgoing s2s connection.
+
+Features yet to be implemented:
+- For 'remote-domain' elements, add domain name _only if_ through service discovery that domain advertises the 'urn:xmpp:serverinfo:0' feature.
+
+Installation
+============
+
+Enable this module in the global or a virtual host.
+
+The default configuration requires the existence of a Pub/Sub component that uses the 'pubsub' subdomain of the host in which the module is enabled:
+
+    Component "pubsub.example.org" "pubsub"
+
+The module will create a node and publish data, using a JID that matches the XMPP domain name of the host. Ensure that this actor is an admin of the
+Pub/Sub service:
+
+    admins = { "example.org" }
+
+Configuration
+=============
+
+The Pub/Sub service on which data is published, by default, is a component addressed as the `pubsub` subdomain of the domain of the virtual host that
+the module is loaded under. To change this, apply this configuration setting:
+
+    pubsub_serverinfo_service = "anotherpubsub.example.org"
+
+The Pub/Sub node on which data is published is, by default, a leaf-node named `serverinfo`. To change this, apply this configuration setting:
+
+    pubsub_serverinfo_node = "foobar"
+
+To prevent a surplus of event notifications, this module will only publish new data after a certain period of time has expired. The default duration
+is 300 seconds (5 minutes). To change this simply put in the config:
+
+    pubsub_serverinfo_publication_interval = 180 -- or any other number of seconds
