There are a number of scenes that ship in the download.  This page breaks down each file and how to use them.
RenderManStudio_Lighting_v01.hip

This scene is the end of the Solaris pipeline and is where the $HIP/usd/Layout/RenderManStudio_Layout_v1.usda file is loaded it.  

As you can see from the stage, a number of lights have been set up to get you started.  The edit node is there for final layout tweaks and a close and wide camera has also been added.

There are two cameras already set up.
