Biscuits joints are ridiculously simple. The only "catch " is to make sure that each piece is dead flat, either by nature or via a little persuasion (i.e. clamps), to make sure the slots line up. I also really like the trick of putting a piece of sandpaper under the joiner when cutting the mating slots in the outer piece, so that it will stand 1/64 proud. That makes it real easy to sand flush. (This assumes you're using the table as the reference surface, not the fence.)
