Newbie question

[AltatemTC]

I am somewhat new to UML and Enterprise Architect.  I am currently setting up a "process" (buzzword) or guidelines on how to use EA.  I have read the tutorial, parts 1 & 2.  In step #2, it says "Map a Use Case Model to the Business Process Model" and later explains that it is a realization connection.

How is this represented?  Do I setup a diagram and drop each of my Business Process Models on it and then the corresponding Use Case Models and then map the realization?  

Thanks in advance.
