Documentation for KUKA Virtual Controller (VRC) available anywhere ?

Hello members of this community, 

I would like to ask if anyone can point me to any sort of documentation that is available for KUKA Virtual Control capabilities with ControlBuild. What I am looking for specificaly is just how to get started and something that can give me a foundational understanding of how this works and can be implemented.
Any tips would be much appreciated !

Regards,

Omar
