I released a WordPress theme under CC0 - No copyright. Well, my code at least. There are plenty of components (
/_assets/ folder) that are under other licenses, but I'm sure you can figure that out.
It's not a theme filled with settings pages or whatnot. If you want to run it on your site, you're gonna have to set up a dev environment, compile the assets and customize to your own liking. In other words: If you have no idea what I just said, this theme isn't for you.
