It's a good place to start. As Colorado mentioned, it is broken up into many steps, lots of steps, but then again, if you don't know the why, just doing the motions won't help to be sure you don't put any holes in the training, eh? It's tedius, yeah, but it's necessary, I think to know everything about, well, everything...or as much as possible.
Anyhow, If you're more the visual learner and want more to the point stuff, Clinton Anderson's ground work dvds have some really great stuff.
Good luck & Have Fun.
