Building Cinder from source currently requires a recent nightly Rust compiler, and cargo-pgo.
rustup toolchain install nightly
rustup component add llvm-tools-previewcargo install cargo-pgomakeYou will find the compiled binary under target/bin/.
Cinder implements the UCI protocol and should be compatible with most chess graphical user interfaces (GUI). Users who are familiar with the UCI protocol may also interact with Cinder directly on a terminal via its command line interface (CLI).
