After reviewing your proposed changes contained in a pull request, the project team may choose to merge your changes contained in a branch of the origin repository into the main branch of their project repository. This merge is accomplished through the GitHub UI in the browser. Once your code as been incorporated to the project repository, you need to synchronize with that repository.
The following code pulls the most recent code from the upstream main branch. Remember to push those changes to your origin as well, so that your cloud repository stays synchronized with the project repository. You have already seen these three commands {select, pull, push} in previous scenarios:
git switch main
git pull upstream main
git push origin main
At this point, you are re-synchronized with the project's repository and you are ready to start making more changes.
It is not uncommon to need to work on two sets of changes at the same time. You can do that by working on two separate branches. All of the steps that we have seen so far work fine with you committing changes on two separate branches.
