Update GitHub fork

Let’s say you want to contribute with a new feature to an open source project hosted on GitHub.

You can fork the repo, edit, test, commit your changes, and finally open a pull request.

After some time your local repo might become outdated. How can you update your fork by getting the most recent version from the main repo?

1. Add a new upstream remote to track the main repo

   1
    $ git remote add upstream git://github.com/octocat/Spoon-Knife.git
   

2. Fetch upstream in your local repo

   1
    $ git fetch upstream
   

3. Merge upstream/master in your current branch to apply the updates

   1
    $ git merge upstream/master
