 Currently the following boards are supported by the library:
 
 * All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
-* Teensy (Teensy++ 1.0, Teensy 2.0, Teensy++ 2.0, and Teensy 3.0)
-	* Note if you are using the Teensy 3.0 you should download this SPI library as well: <https://github.com/xxxajk/spi4teensy3>. You should then add ```#include <spi4teensy3.h>``` to your .ino file.
