Pages, menus and FAQ
Write pages such as About and your policies under Content › Pages, then link them from your header and footer under Content › Menus.

Go to Content › Pages and press New page. Write the Title and Body, then set its Status to published. The screen also offers the standard pages as drafts for you to write, and can add them to your footer.
Menus
Go to Content › Menus and press New menu. Add items with Add item, each linking to an address, product, collection, category or page. Indent and Add sub-item nest them, up to four levels. Then press Save.
FAQ
