Is there some kind of guide or howto on setting up Macaroon? It looks like a pretty useful addon but I'm struggling to work out how to configure it.

Currently I use default Blizzard bars with /cast [target=focustarget] ability macros for every ability. I'd like to eliminate the need for all these macros if possible.

EDIT: Actually I use the focustarget macros for my shammies. For my hunters I use /target [target=focustarget]; /cast ability macros. Can those also be eliminated with the help of Macaroon?
