+# //Reaktor/IRC
+
+This component implements a remote shell daemon that exposes the
+executable files (which may be symlinks) below
+`//Reaktor/public_commands/` through IRC.
+
+## Security
+
+Access to the IRC server implies full access to all the exposed executable
+files. The daemon is executing the commands without dropping privileges.
+
+## Quickstart
+
+ #? /bin/sh
+ set -euf
+
+ export nick="$LOGNAME|$HOSTNAME"
+ export host=irc.freenode.org
+ export target='#tincspasm'
+
+ exec Reaktor/IRC/index
+
+## Environment variables
+
+The following environment variables are processed by `//Reaktor/IRC`:
+
+### nick
+
+Use a specific nickname.
+
+Optional if the node running `//Reaktor/IRC` is part of Retiolum, in
+which case it defaults to `Name` in `/etc/tinc/retiolum/tinc.conf`.
+
+### host and port
+
+Connect to a specific IRC server.
+
+Optional if the node running `//Reaktor/IRC` is part of Retiolum, in
+which case it defaults to `supernode` and `6667` (well, it always
+defaults to these two, but they only make science in Retiolum^_^).
+
+### target
+
+Join a specific channel.
+
+As always, this does the right thing for properly configured hosts: it
+uses the default `#retiolum`, which is the only really relevant
+channel.^_^
