Create a menu for your website by going to Appearance -> Menu. If you already have a menu created, just activate the “menu” boxes.
You can create a new menu in “create a new menu”. Also assign a new menu for the footer.
You can add icons to each link thanks to FontAwesome. Look for the icon, click on it and copy the code that the web gives you in the text field of the menu.
Finish by clicking on Create menu or Save menu.
