To merge branches in GitHub's web interface, you can create a pull request to merge one branch into another. Here’s how to do it:
- Select 'Compare & pull request'.
- Add a title and description if desired. Click 'Create pull request'.
- GitHub will show the changes that will be merged. Review these to make sure everything is correct.
- On the pull request page, click 'Merge pull request'.
- Click 'Confirm merge' to confirm action.
- The branch will now be merged and you can choose to delete the branch after merging if it’s no longer needed.
