Fork the repository you are interested in.

Clone from your personal repository: git clone https://github.com/<me>/<repo>.git.

Add the original repository to your upstream: git remote add upstream https://github.com/<owner>/<repo>.git

Now, pull and merge:

1. git fetch upstream
2. git checkout master
3. git merge upstream/master

You can run these when the project you are interested updates their code.

Next checkout a new branch that describes your feature: git checkout -b <feature-branch>

Make your patches

Ready? Commit your changes git add . and git commit -S -m "commit message"

In the commit, use a helpful format to describe your PR. Good syntax for your message is something like fix: or chore(linter): .

Push to your repository: git push origin <feature-branch>
