I have all my code in a folder in which I want to initialize a git repo for all the code. This folder has many projects. Some projects have a .git folder in them and are a git repository. I want to add all these projects to the top-level git repo.

Even if I can skip the one’s which are already a git repo, can I add the rest of the files automatically?

I have tried:

git add .

This gives me a submodule error.
