Theme Options
Configure global settings, styling, typography, social, and menus.
Navigate to Appearance > Theme Settings in the Admin Sidebar.
The options here are very clear:
General
Here you can add a logo or title and also choose the type of navigation. You can also specify the text in the footer and select the position of the social media icons - in the navigation or in the footer. The Google API Key field is for the Map Shortcode as well as for the Contact Page. The last option is for the Sidebar in the blog and its blog posts.
Styling and Layout
You can style the 404 Error Page here. It can be with a custom background color or a background image. Here you can also change the main colors of the theme and write Custom CSS in this section.
Typography
Select the Heading, Subheading and Body fonts of your site.
Social
The URLs written here will show an icon of the corresponding social network in the footer or navigation, depending on the choice selected in the General tab. These icons are also used in the [Vivian] Social widget for the blog.
Setting Up the Menu
To customize the navigation menu go to Appearance > Menus and customize it as you'll normally do on a WordPress site.
And don't forget to check the Theme Location at the bottom to be Main Navigation after creating your menu.
If you want to add additional pages to the menu like Portfolio click on Screen Options in the upper right corner of the page and check the types that you want to appear as selectables for the menu navigation.
When you are done, click Save Menu.
