+This example is meant for Raspberry Pi and Pi2 and has been tested with Raspbian.
+
+Enable the SPI and I2C interfaces on the Pi.
+
+Install the 'qt4-dev-tools' package, which allows compiling of QT applications.
+
+To build (will build any SDK dependencies as well):
+qmake && make
+
+To clean:
+make sdkclean && make distclean
+
+If you wish to run this application without using sudo, you should add the user "pi" to the usergroup "i2c".
+
+----
+
+In order for the application to run properly, a Lepton camera must be attached in a specific way to the SPI, power, and ground pins of the Raspi's GPIO interface, as well as the I2C SDA/SCL pins:
+
+Lepton's GND pin should be connected to RasPi's ground.
+Lepton's CS pin should be connected to RasPi's CE1 pin.
+Lepton's MISO pin should be connected to RasPI's MISO pin.
+Lepton's CLK pin should be connected to RasPI's SCLK pin.
+Lepton's VIN pin should be connected to RasPI's 3v3 pin.
+Lepton's SDA pin should be connected to RasPI's SDA pin.
+Lepton's SCL pin should be connected to RasPI's SCL pin.
+
