What does it mean by a "photocopy of your driver's license"?

I am filling out a passport application for the first time and it asks me to make a photocopy of my driver's license. Does it simply just ask that i take it to a copier and copy it, or must i have it copied in a specific manor? i understand that i must photocopy the back and front, but i am unsure of the process in how I am to get it done.
