-Foreign Function Interface for Python calling C code.
+Foreign Function Interface for Python calling C code. The aim of this project
+is to provide a convinient and reliable way of calling C code from Python.
+The interface is based on `luajit FFI`_ and follows few principles:
+* Able to call C from Python without introducing a third language
+ (unlike Cython or SWIG)
+* Keep all the python-related logic in Python instead of C (unlike CPython
+* Be complete and work on the level of API (unlike ctypes)
+.. _`luajit FFI`: http://luajit.org/ext_ffi.html
