Actually getting Started with InCopy

I can figure out how and when do masterpage or InDesgin layout elements, document grids, primary text box sizes, etc.  show up in InCopy while writing.

All i find is "you can view you indd layout directly in InCopy"

but how do i do that?

Am i missing a proper introduction to this?

Basically i have just created a icml, imported it into the master text flow in indesign, gave the masterpage a background color and a new margin.

Then i open it up in Incopy again and see no layout changes in the layout view.

So i read about assignments, if i export an assignment the layout is there, the text flow is missing but its window gets a grey background color which i havent set.
