+IRC Mod for Minetest
+====================
+
+Introduction
+------------
+This mod is just a glue between IRC and Minetest. It provides two-way
+ communication between the in-game chat, and an arbitrary IRC channel.
+
+The forum topic is at http://minetest.net/forum/viewtopic.php?id=3905
+
+ 
+Installing
+----------
+
+Quick one line install for linux:
+
+	cd <Mod directory> && git clone https://github.com/kaeza/minetest-irc.git irc && cd irc && git submodule update --init
+
+Please change `<Mod directory>` to fit your installation of minetest.
+For more information, see [the wiki](http://wiki.minetest.net/Installing_mods).
+
+The Minetest IRC mod uses submodules, therefore you will have to run
+`git submodule init` when first installing the mod, and `git submodule update`
+every time that a submodule is updated.  These steps can be combined as
+`git submodule update --init`.
+
+The Minetest IRC mod also requires LuaSocket.  This can be installed using your
+package manager on many distributions, for example on Arch Linux:
+
+	# pacman -S lua51-socket
+
+
+Settings
+--------
+All settings are changed in `minetest.conf`. If any of these settings
+are not set, the default value is used.
+
+  * `irc.server` (string, default "irc.freenode.net")
+	This is the IRC server the mod connects to.
+
+  * `irc.channel` (string, default "##mt-irc-mod")
+	The IRC channel to join.
+
+  * `irc.interval` (number, default 2.0)
+	This prevents the server from flooding. It should be at
+	least 2.0 but can be higher. After four messages this much
+	time must pass between folowing messages.
+
+  * `irc.nick` (string, default "MT-FFFFFF")
+	Nickname used as "proxy" for the in-game chat. 
+	'F' stands for a random base-16 number.
+
+  * `irc.password` (string, default "")
+	Password to use when connecting to the server.
+
+  * `irc.NSPass` (string, default nil)
+	NickServ password. Don't use this if you use SASL authentication.
+
+  * `irc.SASLPass` (string, default nil)
+	SASL password, same as nickserv password.
+	You should use this instead of NickServ authentication
+	if the server supports it.
+
+  * `irc.SASLUser` (string, default irc.nick)
+	The SASL username. This should normaly be set to your main NickServ account name.
+
+  * `irc.debug` (boolean, default false)
+	Whether to output debug information.
+
+  * `irc.disable_auto_connect` (boolean, default false)
+	If false, the bot is connected by default. If true, a player with
+	the 'irc_admin' privilege has to use the /irc_connect command to
+	connect to the server.
+
+  * `irc.disable_auto_join` (boolean, default false)
+	If false, players join the channel automatically upon entering the
+	game. If true, each user must manually use the /join command to
+	join the channel. In any case, the players may use the /part
+	command to opt-out of being in the channel.
+
+  * `irc.send_join_part` (boolean, default true)
+	Determines whether to send player join and part messages to the channel.
+
+Usage
+-----
+
+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.
+
+Messages that begin with `[off]` from in-game or IRC are not sent to the
+other side.
+
+This mod also adds a few chat commands:
+
+  * `/irc_msg <nick> <message>`
+	Sends a private message to a IRC user.
+
+  * `/join`
+	Join the IRC chat.
+
+  * `/part`
+	Part the IRC chat.
+
+  * `/irc_connect`
+	Connect the bot manually to the IRC network.
+
+  * `/irc_disconnect`
+	Disconnect the bot manually from the IRC network (this does not
+	shutdown the game).
+
+  * `/irc_reconnect`
+	Equivilant to `/irc_disconnect` followed by `/irc_connect`.
+
+You can also send private messages from IRC to in-game players.
+
+To do it, you must send a private message to the bot (set with
+the `irc.nick` option above), 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 "proxy" user will reject any
+private messages that are not in that format, and will send back a
+nice reminder as a private message.
+
+The bot also supports some basic commands, which are invoked by sending
+a private message to it. Use `!list` to get a list of commands, and
+`!help <command>` to get help about a specific command.
+
