There is some documentation... but this is mostly just a really good center for scripts/scriptlets (which become VERY useful for examining when your trying to figure out how the heck to do something on your own once you start making your own little scripts, working with other peoples scripts and manipulating them is a great way to start learning how to make your own scripts without head diving in and starting with nothing)
