+# GrovePi Minecraft Controller
+# This is a custom controller for Minecraft, made using the GrovePi.
+# In this example, we show you how to build your own custom Minecraft controller
+# with the GrovePi.
+# See more about the GrovePi at http://dexterindustries.com/grovepi
+# A great reference we used is the MagPi's Essentials Minecraft Guide: https://www.raspberrypi.org/magpi-issues/Essentials_Minecraft_v1.pdf
+'''
+Software Setup:
+  Before we begin, run the following commands to setup:
+    sudo apt-get install minecraft-pi 
+    sudo pip3 install python3-xlib
+    sudo pip3 install pyautogui
+
+Hardware Setup:
+  Setup the GrovePi on the Raspberry Pi.
+  Connect a touch Sensor to port A0.
+  Connect a Joystick to port A2.
+  Connect a touch sensor to Port D3.
+  Connect a touch sensor to Port D4.
+
+To run:
+  1.  Start Minecraft on the Pi.
+  2.  Start a world.
+  3.  Start Python3 (IDLE).
+  4.  Open this file (GrovePi-Controller.py)
+  5.  Click "Run" --> "Run Module"
+  6.  Click back into Minecraft.
