Fixing Detached HEAD in a Git Submodule

When working with Git submodules, you might encounter a situation where the submodule is in a detached HEAD state. This can be problematic if you need to make changes and commit them. Here’s how you can fix it:

Steps to Fix Detached HEAD

1. Navigate to the Submodule Directory

   cd path/to/your/submodule

2. Check the Current Status

   # if the master branch already exists locally:
   git branch -u <origin>/<branch> <branch>
   # else:
   git checkout -b <branch> --track <origin>/<branch>
