I used GitGitGadget to make all of my contributions. This meant that I could make a GitHub pull request (a workflow I’m comfortable with) and GitGitGadget would convert my PRs into the system the Git developers use (emails with patches attached). GitGitGadget worked great and I was very grateful to not have to learn how to send patches by email with Git.
