 The :py:mod:`freenect2` module provides a Python interface to the `libfreenect2
 <https://github.com/OpenKinect/libfreenect2>`_ library. The libfreenect2 library
 provides a library allowing depth and RGB data to be extracted from a Kinect for
 Windows v2 (K4W2) device.
 
-The library is intended to provide an easy to use Pythonic interface to
-libfreenect2. As an example of library usage, here is a simple infrared (IR)
