To update the main menu and remove navigation links that aren’t needed, navigate to WordPress Dashboard>Appearance>Customize>Menus>Main Menu. Here you can add, delete, or reorganize what pages you want to be included in the header menu.

There is a created footer navigation, which can be modified in the same “Menus” area, but the actual menu in the footer was added as a widget due to desired formatting. This can be edited by navigating to WordPress Dashboard>Appearance>Customize>Footer>Widget 3.

The Social Icons menu in the footer will also need to be updated with the links to your social accounts. This can be done by opening WordPress Dashboard>Appearance>Customize>Footer>Widget 6. You can select the social icons block and add any other social icons you need, then click on each icon to set a link for it.
