The separation between the `develop` and `main` branches was inherited
from Tusky and isn't helpful, complicating the release process and
causing CI to repeatedly run the same actions on the same code.
Deprecate the `develop` branch by removing references to it in the
documentation and updating the CI configuration as necessary.
Separately, the GitHub settings will be changed to set `main` as the
default branch, and the `develop` branch will be deleted.
Instead of a single `CONTRIBUTING.md`, create an initial set of more
detailed documentation for the different types of contribution.
Start with `code.md` and `translate.md`, the processes for submitting
code and translations respectively.
Commit to documenting how to contribute documentation, project
management, user support, and social presence in the next week.
Ensure that project decisions are clear and transparent to potential
contributors by documenting them in `docs/decisions`, starting with
the decision to use conventional commits.
Use the MADR format (https://adr.github.io/madr/).
