Best way to fix my crawfish?

Hello I have never tried crawfish before. I have heard they taste kind of between lobster and crab. I love all seafood so Im sure I will like them. I am going to get 2 lbs. from a local seafood store. They won't be alive. Im not near the ocean so im sure they will either be frozen or on ice. What's the best way for me to boil and cook 2 lbs. just for myself? a little recipe will be nice if you can throw it in. Keep in mind this is only for 2 lbs. Im going to see if the store has a seasoning I dump into the boiling water. Thanks for any help.
