Git submodule

To add submodule

$ git submodule add <remote_url> <destination_folder>

• please note that you have to give the full path including the name of folder of the submodule for <destination_folder>

• <destination_folder> is equivalent to <existing_folder>/<submodule_folder>

• by default without <destination_folder>, the submodule folder would be created on the current directory

$ git rm --cached <path_to_submodule> (no trailing slash)
$ rm -rf .git/modules/<path_to_submodule>
