 Resolving a conflict doesn't automatically merge the pull request in GitHub. Instead, it stores the resolution of the conflict in a merge commit and allows you and your team to keep working. To resolve a conflict, GitHub performs what is known as a *reverse merge*. This means that the changes from the `main` branch were  merged into your `my-resume` branch. With a reverse merge, only the `my-resume` branch is updated. This allows you to test the resolved changes on your branch before you merge it into `main`.
