• Joe has a local and a remote repository. https://github.com/joe/demo
• Mary "fork" the repository of Joe creating a remote copy of her own: https://github.com/mary/demo
• Mary clones her remote repository to the local disk
• Mary creates a local branch called 'feature', makes some changes, pushes the changes out to the 'feature' branch in her own remote repo.
• Mary sends a "pull request" to Joe asking Joe to integrate the changes to the master branch of his own repository.
• If Joe has comments, he makes them. Mary can make further changes in the 'feature' branch, and push them out.
• Once Joe is satisfied with the pull-request he accepts it merging the changes to his own "master" branch.
• Mary sets up the remote repository of Joe to be a remote repository of her own. (She only needs to do this once per repo.) git remote add upstream https://github.com/joe/demo.git
• Mary changes to "master" locally, and pulls from Joe: git checkout master git pull upstream master
• Mary can then delete the local and remote 'feature' branch.
• If Mary already has other feature branchese she might want to rebase them onto "master" so they will be based on the most recent changes.
