# ForeignThon > Write Python in any human language. ForeignThon is a transpiler ecosystem that lets developers write Python using keywords and builtins in their native language. ForeignThon is published under the GPL v3 license and is proudly FOSS. ForeignThon is community-built and is open for anybody to contribute. ```bash pip install foreignthon which fpy ``` ## Languages ForeignThon works by adding a language pack on top of the core ForeignThon architecture, and these language packs are available in PyPI as `foreignthon-xx`, where xx is the language code. ```bash pip install foreignthon-es fpy new myproject --lang es cd myproject && fpy run src/main.es.py ``` ## Documentation For a full guide on usage, development, and contribution, please see our docs → [docs.foreignthon.dev](https://docs.foreignthon.dev)
