Change your port name...

[sscirrus]

I find the instructions here unclear - what should we change the port name to? If it's supposed to be something in particular, how can I find out what that should be?

Thank you!

The port should be the serial port of your board as seen in the Arduino software. In the Arduino program, plug in your arduino and look at the Tools> Serial Port menu.
I have updated the Readme with clearer instructions.
See this page for more info on finding this in the arduino IDE on your specific platform:
Mac: http://www.arduino.cc/en/Guide/MacOSX
Linux: http://playground.arduino.cc/Learning/Linux
Windows: http://www.arduino.cc/en/Guide/Windows

Let me know if that helps, thanks!
