Sure! Give me 10 minutes and I can add you as a collaborator. I strongly recommend making a fork of this repo so that you have your own version to make changes to. You can see how to do this in CONTRIBUTING.md. When you finish working, submit a PR from your fork and I will review it. Thanks for helping!

Thank you for your interest. I apologize for the late reply. Consider checking CONTRIBUTING.md to learn how to contribute. I am not comfortable giving people full contributor access to this repo.
