Normally I try not to be a smart ass but have you tried looking on the internet?
Ex: google. type in "WS4SB". Enter.
I'm pretty sure you would have found what you're looking for in less time than it took you to post.
Or for example going to the Westside website and reading the basic articles. Or reading the Dave Tate articles posted like 2 posts above yours with the description "the Dave Tate article that explains everything you need to know".
