+#Display-o-Tron HAT
+
+Display-o-Tron HAT uses both SPI and I2c to drive the LCD display, backlight and touch. 
+However both of these busses can be shared with other devices.
+
+You can use the one-line product installer to get Display-o-Tron HAT set up and ready to go, just:
+
+```bash
+curl get.pimoroni.com/dot3k | bash
+```
+
+And follow the instructions!
