I am writing Guidelines to give projects a guide on how to make a governance that works for their needs!
The Structure is not finished yet (its a pr), but I can offer the Decision Making process that I am confident in. That said I have setup the structure too in a couple of places already so it has undergone practical testing.

Templates, guides and values to structure our spaces by-and-for us, the community, with a dynamic structure (without hierarchies or voting) and participatory processes (plurality, diversity, platforming, etc.)
I have helped setup a couple of communities some tech some not (some of them listed in the repo). I don't have a site myself yet, but I am free to have a call whenever you want.
