SelfCI is _very_ minimal by design. There isn't really all that much to document other than what is described in the README.

> Also, how do you like Radicle?

I enjoy that it's p2p, and it works for me in this respect. Personally I disagree with it attempt to duplicate other features of GitHub-like forge, instead of the original collaborate model of Linux kernel that git was built for. I think it should try to replicate something more like SourceHut, mailinglist thread, communication that includes patches, etc. But I did not really _collaborated_ much using Radicle yet, I just push and pull stuff from it and it works for that just fine.
