Contribution Marquee

2023-08-11 16:21:00

Using PIL ImageFont, Numpy, and a GitHub module, I'm able to create a JSON containing details of when to contribute to a certain project in order to achieve the result. A second script can then take that JSON on a schedule and contribute to GitHub when it needs to.
