What is the process for switching the branch tracked by a git subrepository?

edit

The process for switching the branch tracked by a git subrepository is:

1. Navigate to the root directory of the parent repository
2. Use the git submodule command to access the subrepository: git submodule update --init subrepo
3. Navigate to the subrepository directory: cd subrepo
4. Use the git branch command to list the available branches: git branch
5. Use the git checkout command to switch to the desired branch: git checkout branch_name
6. Return to the root directory of the parent repository: cd ..
7. Update the parent repository to reflect the new subrepository branch: git add subrepo git commit -m "Switch subrepo to branch_name"
