This is just a short post and the title says it all … I’ve wanted add submodules to a Git repository but you get an error if you try. So how do you add a submodule to your root folder in your Git project? Easy - Git Subtree Merge is what you need.
Add your 2nd Git Project as a Remote
Actually, you start by adding a git remote with the source being the git project you want to pull in.
The you do a pull from your Remote … and merge / diff any of the files
