Hi there!
To get the home page set up the way you see in the demo site:
- Publish a new page and assign the Front Page template to it. You can assign the page template from the dropdown menu under the Page Options module.
- Next, navigate to the Static Front Page panel in the Customizer.
- Check the option next to A static page and then choose your newly published home page from the Front page dropdown menu.
- Save your changes and navigate to the Theme Options panel in the Customizer to change the settings for each section of the home page.
You can find further step-by-step guidance for getting set up to look the demo site here:
