Windows:
Run M2RET_Flash.bat You will likely need to have installed the Arduino IDE first
so that it installs the proper drivers.

OSX:
Run M2RET_Flash.command 
OSX should automatically detect the M2 whether you installed the Arduino IDE or not

Linux:
Run M2RET_Flash.sh
Linux should automatically detect the M2 whether you installed the Arduino IDE or not

On both OSX and Linux you might need to chmod +x the script before you can run it.
