+IRC is used by Electrum server to find 'peers' - other Electrum servers. The current list can be seen by running:
+
+./server.py peers
+
+The following config file options are used by the IRC part of Electrum server:
+
+[server]
+irc = yes
+host = fqdn.host.name.tld
+ircname = some short description
+
+'irc' is used to determine whether the IRC thread will be started or the Electrum server will run in private mode. In private mode, ./server.py peers will always return an empty list.
+
+'host' is a fqdn of your Electrum server. It is used both when binding the listener for incoming clien conections, and also as part of the realname field in IRC (see below).
+
+'ircname' is a short text that will be appended to 'host' when composing the IRC realname field:
+
+realname = 'host' + ' ' + 'ircname', for example 'fqdn.host.name.tld some short description'
