document this project
This project is really nice, but could use some documentation, at least a README file with information about what to do with @renovate-bot specifically. Like right now I have !14 (closed) in my queue and i have zero idea how to evaluate it, which makes my review useless rubber-stamping. What I would like to see is information like where that image was built, what the diff means, how i can evaluate it, maybe make my own diff between the two containers and so on.
also some basic information about the project's mechanics would be nice.
