You are looking at the generated documentation for the code of The Penguins Game project. If you are interested in playing the game itself, you might want to check out the README of the project on Github instead. I mean, the README is a good place to see anyway as it contains some notes on the design and architecture of the project as well.

A good place to begin familiarizing yourself with the codebase from are the Game and BotState structs and their associated functions.
