+// EnableInterrupt HiSpeed example sketch
+// See https://github.com/GreyGnome/EnableInterrupt and the README.md for more information.
+
+// This example demonstrates the use of the EnableInterrupt library on a single pin of your choice.
+// It uses the "HiSpeed" mode of the library.
+// This has only been tested on an Arduino Duemilanove and Mega ADK.
+// It is designed to work with the Arduino Duemilanove/Uno, Arduino Mega2560/ADK, the Arduino
+// Leonardo, and the Arduino Due. Please let me know how you fare on the Leonardo or Due.
+
+// To use:
+
+// 1. You must be using a fairly recent version of the Arduino IDE software on your PC/Mac,
+// that is, version 1.0.1 or later. Check Help->About Arduino in the IDE.
+
+// 2. Wire a simple switch to an Analog or Digital pin (pin 8 in the example below)
+// that supports interrupts. See https://github.com/GreyGnome/EnableInterrupt/wiki/Usage#Summary
+// Attach the other end to a GND pin. A "single pole single throw momentary contact normally
+// open" // pushbutton switch is best for the most interrupting fun.
+// See https://www.sparkfun.com/products/97 and https://octopart.com/b3f-1000-omron-3117
+
+// 3. When pressed, the switch will connect the pin to ground ("low", or "0") voltage, and interrupt the
+// processor. See http://arduino.cc/en/Tutorial/DigitalPins
+
+// 4. The interrupt is serviced immediately, and the ISR (Interrupt SubRoutine) sets the value of a global
+// variable. Open Tools->Serial Monitor in the IDE to see the results of your interrupts.
+
+// 5. Peruse the Examples directory for more elaborate examples.
+
+// 6. Create your own sketch using the EnableInterrupt library!
+
+// Refer to
+// https://github.com/GreyGnome/EnableInterrupt/wiki/Usage#Summary
