Manual? + Requirements?

[Warmskin]

I d/l'd the demo and I'm enjoying this quite a bit so far. I sure would like to have a look at the actual full manual before I buy it... Is there a PDF file or something somewhere for this game (the new 2008 version, of course)? Also, I have a pretty old computer, but the demo seems to run just fine so far. Can I expect the same from the full version once I purchase it? Thanks a lot. And *no*, I am not a pirate. I just want to know before hand if this will work on my machine and *how* the actual mechanics work, because so far, I don't really see any tutorial. Thanks very much.
Old P4 (~ 4 years old), 3.2 GB, 2 GB ram, 7800GS video... First half hour of the demo runs well. Thanks, guys.
