How to remove submodule from Git

Git allows you to include other repositories for your project as a submodule, however, I've encountered an errors. To remove them cleanly, follow these steps below.

1. Open root directory of project

   cd path/to/project

2. Move module to a temporary directory

   mv path/to/[module] path/to/[module]_tmp

3. De-initialize submodule

   git submodule deinit -f -- path/to/[module]

4. Remove from Git modules

   rm -rf .git/modules/path/to/[module]

5. Remove from Git repository

   git rm -rf path/to/[module]

6. Remove temporary directory

   rm -rf path/to/[module]_tmp
