Hello everyone curious enough to visit this unmaintained implementation of chess in rust. I have taken it upon myself to fork this repo and maintain it. If you would like to contribute, please create a pull request at https://github.com/Orkking2/chess/pulls, unlike jordanbray, I have not been inactive since 2022 😅. If you'd like to see what changes I have implemented, feel free to peruse this pull request, as it is not likely to be accepted.
