You could use pages to give your customers additional information such as 'About Us', 'Contact', 'Wishlist', 'Term & Conditions', 'Shipping information', 'Refund information' or even create specific pages such as 'Landing page'. The pages are an easy way to communicate with your customers. To access those pages you could use Navigation.
Foodly theme has pre-defined templates for 'Contact', 'Wishlist' and 'Landing page' pages.
