Improve Git documentation for contributors
Type of work:
This is about:
- documenting how to get a new Git repo;
- adding troubleshooting / contact info so that contributors reach out to the right people when they need help;
- documenting how to initialize a git-remote-gcrypt repo.
I've drafted something, may you please review:
Thanks in advance! If you prefer not to handle this yourself, fine: just reassign to me and I'll find someone else :)
