6. Switch to the master branch and synchronize with the original repository:

7. Switch to the dev branch, merge the local master branch (which is now synced with the original repository), resolving any conflicts if needed:
$ git checkout dev
$ git merge master
8. Push the local dev branch to your remote dev repository:
$ git push origin dev
