The documentation lives in the `docs` folder and uses
[mdBook](https://github.com/rust-lang/mdBook). Please document new user-facing
features here!
Using [GitHub actions](https://github.com/features/actions), the documentation
on `master` is automatically published to [the project
homepage](https://hakoerber.github.io/git-repo-manager/) via GitHub pages. See
`.github/workflows/gh-pages.yml` for the configuration of GitHub Actions.
