Everything surrounding code: issues, CICD, etc, is obviously another story. But it's not a story that is answered by distributed git either. (though I would love a good issue tracking system that is done entirely inside git)
You might like git-bug:
This should be one of the very first links in the readme.
i rewrote the README with the goal of providing a clear overview of git-bug's features, and why you might want to use it, and ensuring that for those who are more technically inclined, things like the data model, internal architecture, and more were easy to find under the documentation folder (whether you're browsing through the files directly, or landing on //doc:README.md, which links to the files and folders under //doc.
if you think that there is information missing from the README, or hard to find in the repository (either by browsing through it, or clicking the rather prominent links from the main README), i'd welcome any suggestions in the form of a PR.
