What is the correct way to wear a claddagh ring?

I was hoping that maybe one of you guys would know the answer to this.

I've had several different people tell me several different ways that are the "correct" way to wear a claddagh ring. I've gotten so confused by all the different "right" ways that I don't know what way mean what. Can somebody straigthen it out for me?

Thank you.
