Hello @jws236,
First of all, thank you very much for using the theme.
Now to edit the navigation, just go to Admin panel < Appearance > Menus and edit the menu as per you requirement.
As for the footer section, the option to edit the footer content is only available in the pro version.
With the free version, you will be only able to edit the setting of the scroll button.
Hope this clears the confusion.
If you have any query/confusion further then kindly let us know.
Thank you.
