Ghost makes it easy to update your navigation menus, so you can quickly make updates such as adding an about page to your main navigation, or a contact page in your footer.
Your site's navigation menu can be updated directly in Ghost Admin from the Settings → Site → Navigation section. By clicking on Customize, a new menu will pop up which allows you to add or edit items in your primary & secondary navigation.
If your theme supports it, you can also secondary navigation links to your publication. These are commonly used in your footer, or in the top right corner beside your primary navigation.
