+--- **AceConsole-3.0** provides registration facilities for slash commands.
+-- You can register slash commands to your custom functions and use the `GetArgs` function to parse them
+-- to your addons individual needs.
+--
+-- **AceConsole-3.0** can be embeded into your addon, either explicitly by calling AceConsole:Embed(MyAddon) or by 
+-- specifying it as an embeded library in your AceAddon. All functions will be available on your addon object
+-- and can be accessed directly, without having to explicitly call AceConsole itself.\\
+-- It is recommended to embed AceConsole, otherwise you'll have to specify a custom `self` on all calls you
+-- make into AceConsole.
