How to cite? #390
Description
I couldn't find a recomended way of citing this guide. It would be nice to include a cff citation file in the repo:
https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-citation-files
And also provide a citation in the "credits" section or similar:
