Why would you track an empty directory with Git?

Question

I've seen people adding .gitkeep, .keep files in empty directories on a Git repo and I just don't see why I would ever need to track en empty dir.

Can you mention some examples where that would be necessary?

Answer 1

When creating a template project for others to implement it may be convenient to include empty directories to help guide where certain content should go.

For example, an MVC template repo could include empty model, view, and controller folders that are already in the correct location and ready to be filled with files.
