First, mark where you need to cut the hole for the duct: I placed the hood inside of the bin and propped the "neck" part of it up with a wad of paper to keep it in place so I can trace it from inside of the hood with a pencil. I prop the neck so the ductwork will exit the bin parellel to the bottom instead of it tilting down.
