How Do I Cut Crown Molding For Wall Cabinets? I Need To Know How To Do Outside Corners?

I'm installing crown molding on wall cabinets and would like advise on how to properly mount the crown molding to the top of the cabinets. I was told by one contractor to attach the crown molding to plywood and have the crown molding rest on top of the cabinets like a hat. What would be your advise for installation?
