Is there a way to easily set the site to match the sample layouts?  I'm looking to use layout 15 but not sure how to easily implement.  (I've installed the basic demo already.)

 

Sorry if this is a really silly question.

Hello customer,

Sorry for lately reply. About your question:

if you want page XYZ (node/1) match to layout 1. Just edit this layout and input node/1 to Pages Assignment textarea. All pages which have not assigned will have Default layout

You can reference to http://docs.drupalexp.com/palas/#!/layout-settings for more detail

Thank you
