I'm writing a chess engine in C# for school purposes. As part of the assignment, I need to read something from an external document. I was thinking of reading an opening book, but I can't really find much documentation because Polyglot is used a lot of the time. I can't really use that because I don't get marks for other people's code.

Does anyone have information or a good website on how to implement a png/bin opening book in your chess engine?
