All documentation is available on GitHub:
I’ve been keeping an eye in the GitHub organization for a while but it seems very inactive from the outside, no issues, no PRs, no roadmaps, no contribution guidelines…
I’m sorry to hear this. There are some issues already (mostly community members willing to create localizations of the OS). Maybe you get the feeling that nothing is happening because most of the core dev team discussions happen on Jira/Confluence which are currently closed to the public.
When it comes to PRs - are you looking in the right section? We currently have 30+ of them but the number is always dynamic since we release a new version of MuditaOS every week (visit our releases section with changelogs for every release).
We also plan to provide the community with a general roadmap after Mudita Pure is made available to the public.
I hope this helps. Feel free to share any additional feedback.
All the best!
