I've got the capacitive touchscreen working, being from adafruit, it requires a bit more with regards to its set up then I guess the official raspberry Pi screen does. However Raspberry Pi themselves do not sell screens this small, that I'm aware of?

I will upload instructions on the adafruit screen set up, these should apply for any of the adafruit capacitive touchscreens. It involves the downloading of a few libraries, the manipulation of some root pi files and some play with the calibration. This is to have the screen work with Kivy as well as the GUI has been coded in this. I will upload instructions on installing Kivy on the Pi too as well to help anyone if needed. 

Here it's just displaying the Raspbian desktop. Shoutout to Arduino in the background.
