You can submit a pull request in GitHub
As a general rule for any contribution: please make sure you provide as much information as you can to ease collaboration and follow the instructions noted in the CONTRIBUTING.md file of the repository you plan to contribute to. When creating a pull request, follow the Pull Request Checklist available in the respective CONTRIBUTING.md to ensure reviews can happen promptly. Also, if you plan to do something more involved, please reach out to us and send an email first. This will avoid unnecessary work and give you and us a good deal of inspiration.
