+## Installation
+### Installing kociemba
+The kociemba program produces a sequence of moves used to solve
+a 3x3x3 rubiks cube.
 ```
-sudo apt-get install build-essential python3-pip libffi-dev

-### Running
-./rubiks.py
+### Installing rubiks-color-resolver
+When the cube is scanned we get the RGB (red, green, blue) value for
+all 54 squares of a 3x3x3 cube.  rubiks-color-resolver analyzes those RGB
+values to determine which of the six possible cube colors is the color for
+each square.

+$ sudo apt-get install python3-pip
+$ sudo pip3 install git+https://github.com/dwalton76/rubiks-color-resolver.git

+
+### Installing the MINDCUB3R demo
+We must git clone the ev3dev-lang-python repository.  MINDCUB3R is included
+in the demo directory.
+```
+$ cd ~/
+$ git clone https://github.com/rhempel/ev3dev-lang-python.git
