Cisco MC3800 commands

Hi, I need help. Here at office we use cisco router MC3800, and uses frame relay connection for our branch. I'm a newbie in cisco, so can anyone tell me where's the best links to learn on the web about cisco sintaks and commands, because I want to learn it online.
Also about the frame relay topology, so I can learn.

Thank you and regards,
