The basic step when committing to open source projects is to fork the project.
Then the process is easy you create your branch and you make a pull request. However from time to time you need to adjust you branch based on the latest changes.
This is how you sync your fork to the original one.
git fetch upstream git checkout master git merge upstream/master
This is pretty easy but you might want something more than just synchronizing with the original repository.
For example there might be a pull request which never got merged for various reasons and you wan’t to pick up from where it was left.
The first step is to add the repository needed
git remote add $remote_repo_identifier $remote_repo_url
So we just added another remote to our repository.
The next step is to fetch the branches from the remote.
git fetch $remote_repo_identifier
Then you can switch to the branch of your choice, continue make a new branch and continue with a pull request.
git fetch $remote_branch
Remove the upstream
git remote remove $remote_repo_identifier
And set the upstream to your original one
git push --set-upstream origin $remote_branch
