The only hard part is that you've got to get a big crescent wrench or pipe wrench onto the square extrusion on the belt tensioner and relieve the pressure so that you can slip the belt off (and back onto) the alternator. Once you've done that (the tensioner is one of the small pulleys on the side of the engine that the belt is wrapped around - it's very firm but WILL move with enough pressure; WATCH your knuckles!!! If you slip it can hurt like heck!)it's a simple matter of pulling the wiring plug off and undoing the bolts that hold the alternator.
There should be a belt/pulley diagram sticker on the radiator support near the front of the car that will show you the belt routing, make sure that the belt goes back on the right way around the proper pulleys! It can take a minute to make sure you've got it wound round everything the right way (and again, watch your knuckles with that tensioner!) Good luck!
