fooskill is a work-in-progress web app for managing foosball leagues and leaderboards using Django, the Django REST Framework, and React. Details about the rating system, setting up a fooskill dev server, and how to contribute are available in the docs.
The backend for fooskill is 100% finished. However, the frontend is still in development. Currently, the project is on an unofficial hiatus (waiting for a replacement foosball table in our school's common room, should one arrive).
