random numbers

I'm very much a beginning programmer, studying Haskell. I have two questions - Firstly, I am trying to generate random numbers in Haskell, but although I have found a 'random' library on www.zvon.org, I don't really know how to include library functions, and the documentation given doesn't really tell me the effective difference between all the functions provided in the library. In another interesting development, I couldn't find any mention of this library in haskell.org's list of libraries. Secondly, but perhaps more importantly, is there a more 'beginnerish' list that I should be addressing this to? I've been following discussions on this one and they don't seem to be at quite this level. Thanks Jac
