+
+## Installation
+
+Download the [latest
+release](https://github.com/irccloud/irccat/releases) from Github, put
+the [example
+config](https://github.com/irccloud/irccat/blob/master/examples/irccat.json)
+in `/etc/irccat.json` or the local directory, and run!
 
 ## TCP → IRC
 Just cat a string to the TCP port - it'll be sent to the first channel
 ## IRC → Shell
 You can use irccat to execute commands from IRC:
 
-    ?commandname arguments
+    ?commandname string of arguments
 
 This will call your `commands.handler` script with the command-line
 arguments:
 
-    nickname, [channel], respond_to, commandname, [arguments]
+    nickname [channel] respond_to commandname [string of arguments]
 
 irccat will only recognise commands from users in private message if
 the user is joined to `commands.auth_channel` defined in the config.
