Remove Git Sub-module
Simple and to the point, I just dont want to forget how to remove a git submodule again

To remove a sub-module you need to:
- Delete the relevant section from the .gitmodules file.
- Stage the .gitmodules changes
git add .gitmodules
- Delete the relevant section from .git/config.
- Run
git rm --cached path_to_submodule
(no trailing slash). - Run
rm -rf .git/modules/path_to_submodule
(no trailing slash). - Commit
git commit -m "Removed submodule <name>"
- Delete the now untracked submodule files
rm -rf path_to_submodule
