Wow, there's no, like, "getting started" or "how to set up a dev env" section in either the README.md or the CONTRIBUTING.md for #pixelfed 😕
There's some Docker related stuff in the repo, but there are also tickets talking about using some other repo if you want to use Docker with it.
I reported a bug today, but the odds that I'm going to actually try to fix it myself this week are dropping.
