Developing with the Electron FW

Has anyone here built anything against the Electron framework? Good? Bad? Indifferent? Things I should look out for?
I have an idea for something I'd like to develop, I think Electron would be a good fit or what I have in mind - but my knowledge of it is limited. My main concern would be about file access to the local system and possibly compressed files. Atom is built on Electron as I understand it, so local file access shouldn't be a problem, right?

Does anyone have any resources that would be good to start off with?
