I need help with the Denver/Westminster transit system?

I have only been in the Denver area for almost three months and have not needed to use the bus rout yet, I picket up some rout maps, and they are the most confusing maps I have ever seen from northern Cali, to Portland, to Seattle, to Boise. Is there a good place to look to help me figure out how to get around on them? Please help. Much thanks!
