Vale: enforcing style guidelines for text

What about the license for the style (yaml) files that you get in the "styles/" directory after running "vale sync"? I can't seem to find licensing information about them.

Anyway, I guess if we want to use Vale in a documentation project, we can only add the ".vale.ini" file to the repository, and assume that each contributor running Vale will have to run "vale init" first. Therefore, we don't need to add the standard style files to the documentation repository. Is that what projects using Vale are doing?
