 Installation
 ============
 
-Find your Arduino IDE's libraries directory. Then unzip the project
-archive into it. It should end up looking like this:
+1. Find your Arduino IDE's sketches directory.
+
+1. If there isn't already one, create a `libraries` directory inside the sketches directory.
+
+1. Unzip the project archive into `libraries`. It should end up looking like this: `[Your Arduino sketches directory]/libraries/G35Arduino/G35.h (etc.)`
+
+1. Restart your Arduino IDE and you should see G35Arduino among the libraries.
 
-[Your Arduino documents directory]/
-  libraries/
-    G35Arduino/
-      G35.h (etc.)
+1. Upload the BasicExample sketch to your Arduino. You should see the pin-13 LED flicker as the sketch tries to send data to your lights.
 
-Then restart your Arduino IDE and you should see G35Arduino among
-the libraries.
+1. Chop off the stock controller on your lights, being careful to note the function of the three leads from the first light (from left to right looking at the first light pointing upward, they're V+, DATA, and GND).
