First of all install update and upgrade your system:
$ sudo apt update
$ sudo apt upgrade
Then, install required libraries:

Instructions tested with a Raspberry Pi 2 with an 8GB memory card. Probably also works fine on a Raspberry Pi 3.
Download the latest Raspbian Jessie Light
image. Earlier versions of Raspbian won't work.
Write it to a memory card using Etcher, put the memory card in the RPi and boot it up.
