Kingly

Kingly is a UCI compliant chess engine written in Rust.

How to use

Install Rust through rustup and run with cargo:

cargo run --release

Note: For now, the version of rust required is not stabilised, so it might be necessary to switch to the beta branch with

rustup toolchain install beta

For a graphical experience, add Kingly to your favorite UCI compliant GUI, e.g. Arena.
