In this session we will review in details how to set up layouts for various url paths
Enter a new URL path.
This creates a NEW stand-alone blank page on your site that is defined solely by the layout, you can add any blocks in this new layout
Enter a previously registered “system path”- This allows you to set up layouts for node/%, term/%, set layouts for views, etc.
