Adorn - Navigation Menu
Navigate to Dashboard > Appearance > Menus and create a Custom Menu.
Select the items you wish to add to the menu, and click “Add to Menu”.
Drag and drop the items into the order you wish them to appear.
Assign your menu to a Theme Location at the bottom of the menu.
In the Adorn theme, the navigation at the top is the Primary Navigation and the one in the footer is the Secondary Navigation. You can choose to use one or both.
More information on setting up the Navigation Menu can be found here.
