CircleCI Releases architecture

Hey folks!

I’m exploring the new releases kubernetes controller (can’t link to the docs, but it’s at /docs/release/releases-overview/) as a means to control releases/rollouts from circleci and I’d love to learn more about the controller’s specifics (like what resources it watches, etc) but I can’t seem to find a satisfying document/conversation that gets into the specifics of this new functionality. Any chances you’d be able to help me out here so I can make an informed decision about adding this controller to our clusters?
