I am trying to understand how to use https://projectile.readthedocs.io/en/latest/projects/#customizing-project-root-files but it is not clear yet.
My goal is to have nested git projects. Let's say I have a directory structure like /a/{b,c}. Folders a, b and c have been created using git clone and all contain a .git folder. From project a, I'd like to be able to use projectile-find-file over files of a, b and c.
Is it possible? Am I looking at the good documentation? Is it possible to enable this behavior only from one directory by using .dir-locals.el?
