+Once the game is connected to the IRC channel, chatting using the `T` or
+`F10` hotkeys will send the messages to the channel, and will be visible
+by anyone. Also, when someone sends a message to the channel, that text
+will be visible in-game.
+
+### Chat Commands ###
+
+* `/irc_msg <nick> <message>` -- Sends a private message to a IRC user.
+  For security reasons, users cannot send messages to any nick which
+  ends in either `Serv` or `Bot` (case insensitive).
+* `/join` -- Join the IRC channel.
+* `/part` -- Part the IRC channel.
+* `/irc_connect` -- Connect the bot manually to the IRC network.
+  Requires `irc_admin` privilege.
+* `/irc_disconnect` -- Disconnect the bot manually from the IRC
+  network (this does not shutdown the game).
+* `/irc_reconnect` -- Equivalent to `/irc_disconnect` followed
+  shortly by `/irc_connect`.
+
+### Sending Messages to In-Game Users ###
+
+You can also send private messages from IRC to in-game players, though
+it's a bit tricky.
+
+To do it, you must send a private message to the bot (set with the
+ `irc.nick` [option](Settings)), in the following format:
+
+`@playername message`
+
+For example, if there's a player named `mtuser`, you can send him/her
+ a private message from IRC with:
+
+`/msg server_nick @mtuser Hello!`
+
+To avoid possible misunderstandings (since all in-game players use the
+same IRC user to converse with you), the bot will reject any private
+messages that are not in that format, and will send back a nice reminder
+as a private message.
+
+### Bot Commands ###
+
+The bot also supports some basic commands, which are invoked by sending
+a private message to it.
+
+* `!help [<command>]` -- Get a list of commands, or help about a specific
+  command.
+* `!players` -- Get a list of players currently in game, and which are
+  currently "joined" to the channel.
+* `!whereis <player>` -- Return the location of the given player.
