Is there some guidance on stepping through CI-enabled code?

Hi,

Along with tutorials and hands-on practice, I'm trying to trace through some of the practice modules I'm using with CodeIgniter.

The problem, as with many libraries, is that it's easy to dig down too deeply.  I'd like to see the flow of e.g. url routing, by watching it happen in my sample code.

Are there any tutorials that run through a debugging session, showing how everything is expanded and translated?



Regards,
