As an example, let's suppose you want to allow the users of your website to access easily the concrete5 IRC channel.

To do this, you have simply to:

1. install this package
2. add the IRC Chat block type to a page of your site
3. Specify that you want to use Freenode IRC Network
4. Specify #concrete5 as the IRC channel

All done! Now when browsing the page, your users can connect to the concrete5 chat room in a few seconds, without tne need of external programs or plugins!
