How can I get out of the manual and into the actual application?

[eluser]Unknown[/eluser]
I've just installed CodeIgniter and read the manual (since it was the only link on the page when I opened the URL where I installed it).

I'm now bored with the manual and would like to start doing some of the things that it was talking about but there seems to be no link to open the application? Even the 'Getting Started' page was no help?

Is there really an underlying application or is it just all hot air?!

Kind regards

Peter
