For me the sync between lemmy and https://joinpeertube.org/ is still not working flawlessly. syncing new posts from peertube to lemmy suddenly stops working. When I force a sync by searching a new post from a subscribed peertube channel through Lemmy, syncing works for a while, and the the problem described above occurs.
You could also use fossil as SCM, it is small, a single executable and has a wiki (and bug tracker) in it, so you could keep your documentation and code close together
What about creating a dedicated thread for that and for every release, all contributors are listed and appreciated. Additionally there could be a static text that mentions all the other volunteer's who contributed and helped indirectly
🤣👌
