Config a remote for my fork

$ cd my_local_repo

$ git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git
    # Specify a new remote upstream repository that will be synced with the fork

$ git remote -v
    # Verify the new upstream repository specified for my fork

Sync my fork locally

$ cd my_local_repo

$ git fetch upstream
    # Fetch the branches and their respective commits from the upstream repository
    # Commits to master will be stored in a local branch, upstream/master

$ git checkout master

$ git merge upstream/master
    # Merge the changes from upstream/master into your local master branch
    # brings your fork's master branch into sync with the upstream repo
