I'd suggest starting at litestep.com and litestep.nfo. Just reading around. Also, before you actually install it, it's a good idea to read any readme's that come w/. I actually was reading a really good site earlier but alas, that was at work and so I can't get it right now.

However, I just installed it and then read up later when I needed to know stuff or was bored. That works too, but it usually contains a slight bit more time/hairpulling.
