+To setup the project and upload the Arduino usbserial application firmware to an ATMEGA8U2 using the Arduino USB DFU bootloader:
+1. unpack the source into LUFA's Projects directory
+2. set ARDUINO_MODEL_PID in the makefile as appropriate
+3. do "make clean; make"
+4. put the 8U2 into USB DFU mode:
+4.a. assert and hold the 8U2's RESET line
+4.b. assert and hold the 8U2's HWB line
+4.c. release the 8U2's RESET line
+4.d. release the 8U2's HWB line
+5. confirm that the board enumerates as either "Arduino Uno DFU" or "Arduino Mega 2560 DFU"
+6. do "make dfu" (OS X or Linux - dfu-programmer must be installed first) or "make flip" (Windows - Flip must be installed first)
+
+Check that the board enumerates as either "Arduino Uno" or "Arduino Mega 2560".  Test by uploading a new Arduino sketch from the Arduino IDE.
