How do I remove a submodule from my github repository?

Question

I happened to change a name of a directory within my local repository and then proceeded to push this change up to my github repository. In effect, it caused this repository to turn into a git submodule which is displayed as a green icon on github and there is no way to drill down further in to the directory to view individual files.

How do I remove the submodule from github?

Answer 1

Remove the directory as file.

git rm --cached path/to/directory

Note that you don't use a trailing slash. This will delete the special file that point to the commmit in the subrepository.

Remove the .git folder inside the /path/to/directory before re-adding the directory into the index.
