Please include instructions on how to use keep-sorted

I'd like to have https://github.com/google/keep-sorted get invoked whenever I save a file, rather adopt https://pre-commit.com/

Could you include some instructions on how to do so?

No file is named in the issue; start by locating the repository's documentation and reviewing the linked keep-sorted project alongside the mentioned pre-commit approach. Add instructions for invoking keep-sorted when a file is saved, and ensure the documented steps are sufficient to follow.
