# More of a reference of using jinaj2 without actual template files.

#
# Of course you will need to "sudo pip install jinja2" first!

  • 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).

  • Delete the now untracked submodule files rm -rf path_to_submodule
