This is easily achieved by downloading
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

For improved performance consider installing numpy.
For the Pillow Examples, you will need to be running CPython. This means using a Single Board Computer
such as a Raspberry Pi or using a chip such as an FT232H on Linux, Window, or Mac. CircuitPython does
not support PIL/pillow (python imaging library)!

For improved performance consider installing NumPy.
