How to add accelerometer controls to this script?

Hi,

New to unity and scripting and have to make a simple game for my university course. I've been using this script that i've found online for a plane but I need the controls to use the accelerometer for the planes controls so tilt left fly left, tilt up fly up etc... Any idea on how to put this into this script as I do not have a clue and this is due in in a couple of weeks?

Thanks

Chris
