If you have a UC520 you can try Configuration Assistant.
Otherwise, this is the most basic configuration you can use to get CME to work (to save some documentation time):
telephony-service
ip source-address A.B.C.D
max-dn X
max-ephones X
ephone-dn 1
number 1000
ephone 1
mac AAAA.BBBB.CCCC
type
button 1:1
You can use the CME GUI as well.
Here is the CLI admin guide:

Enabling the GUI:

You can also use Cisco Configuration Professional. This is the addition to the UC520 version of Configuration Assistant. I'll be honest - never used this. I know the CLI, however. Here's the product guide, download link is towards the right:
