Building Cinder from source currently requires a recent nightly Rust compiler.
Follow the steps below to build a binary optimized for your CPU architecture.
You'll find the binary under target/bin/.

The efficiently updatable neural networks (NNUE) Cinder uses for position evaluation are trained with bullet, by Jamie Whiting, using data generated by the Leela Chess Zero project, which is available under the Open Database License (ODbL)
Cinder's implementation of the Syzygy tablebases probing algorithm is based on a fork of shakmaty-syzygy, by Niklas Fiekas.
