How to set up Toolbox as git repository?

I have a need to share toolboxes with coworkers and allow everyone to easily update them. To accomplish this, I would like to set up multiple toolboxes with git source control connected to GitLab remote repositories. It would be nice to be able to clone a remote repository and register that as a toolbox, but I don't think that is possible. One way to do it is

1. Package a toolbox from source code
2. Install toolbox
3. Initialize git repository in toolbox directory and add the remote
4. Delete toolbox files that came from the package
5. Git pull

This process is a little bit complicated. Has anyone come up with a simpler solution?
