+
+This document lists and describes the "IRC capabilities" that ngIRCd supports
+and can be requested by a IRC/IRCv3 client that supports the "CAP" command.
+
+ngIRCd implements the "IRC Client Capabilities Extension" as described here:
+<http://www.leeh.co.uk/draft-mitchell-irc-capabilities-02.html>
+
+
+I. Supported Capabilities
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+None. At the moment, ngIRCd supports the "CAP" command and its sub-commands
+but offers no capabilities that could be requested by a client.
