To sync changes you make in a fork with the original repository, you must configure a remote that points to the upstream repository in Git.

  1. Open TerminalTerminalGit Bash.

  2. List the current configured remote repository for your fork.

    git remote -v
    origin  https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
    origin  https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)
    
  3. Specify a new remote upstream repository that will be synced with the fork.

    git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git
    
  4. Verify the new upstream repository you've specified for your fork.

    git remote -v
    origin    https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
    origin    https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)
    upstream  https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (fetch)
    upstream  https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (push)
