[arch-haskell] documentation

Hi all, I have been away from [haskell] for a while while running on the haskell platform and cabal-install for all the extras. I recently wiped my computer, however, and thought I'd give the new arch-haskell system a spin. That said, I'm having trouble figuring out what exactly that system is. I already have ghc and xmonad installed from [haskell], but I'm having trouble figuring out the new way of installing packages which are not in [haskell]. I'm under the impression that cblrepo is involved in some way, however, I am not sure exactly how it is supposed to be used. Where might I find some documentation that could get me started? Thanks, Michael
