What is the bare minimum tags required for an atom feed to be valid? I admit I haven't finished reading the specification yet, but thought that a short summary would be nice for me and anyone else looking for a short, clear answer.

A minimal, valid example is the first thing in the Atom specification. Start with that, then read the rest of the spec to improve your understanding and answer any questions.
