Let's assume your new command is named foo.

1. Write a bash script under ./bin called git-foo. The script should be started with #!/usr/bin/env bash.
2. Read ./man/Readme.md and write documentation for git-foo.
3. Don't forget to introduce it in Commands.md.
4. Update ./etc/git-extras-completion.zsh. Just follow existing code.
5. (Optional) Update ./etc/bash_completion.sh.
6. Run ./check_integrity.sh foo to check if all done.
