+LedControl
+==========
+LedControl is an [Arduino](http://arduino.cc) library for MAX7219 and MAX7221 Led display drivers.
+The code also works with the [Teensy (3.1)](https://www.pjrc.com/teensy/)
+
+Documentation
+-------------
+Documentation for the library is on the [Github Project Pages](http://wayoda.github.io/LedControl/)
+
+Download
+--------
+The lastest binary version of the Library is always available from the 
+[LedControl Release Page](https://github.com/wayoda/LedControl/releases) 
+
+
+Install
+-------
+The library can be installed using the [standard Arduino library install procedure](http://arduino.cc/en/Guide/Libraries#.UwxndHX5PtY)
