Yeah, and there are pics out there showing what exactly is done but they're not the easiest thing in the world to find. Plus I have no idea if your actually suppose to find them. I have them, but I sure as heck am not going to be the one to post them up since I have no idea where they came from. lol
But what is your 'general idea' of how it works? Maybe I can help point you in the right direction or let you know if your already right.
