+## Python binding
+
+On top of the C++ engine, this project also includes the python binding [pyffish](https://pypi.org/project/pyffish/), which can be used as a chess variant library in python, like in the [pychess server](https://github.com/gbtami/pychess-variants). Pyffish is a lightweight wrapper around Fairy-Stockfish, only adding a single [source file](https://github.com/ianfab/Fairy-Stockfish/blob/master/src/pyffish.cpp). It supports move, SAN, and FEN generation, as well as checking of game end conditions.
