Pages
Your site includes unlimited pages. You can use the Page Builder for creating much more advanced layouts or opt-out to use the default/simple page editor.
To add new pages to your site, and remove or modify existing ones, go to the Pages screen from your site settings panel.
When you edit any page, you'll be able to add a title, the actual page URL (slug), add a background image, and modify the content area.
The page editor includes a few custom components like the Episode List, Contact Form etc. so you can add those elements to any page.
If you are not ready to publish your page, make sure to change the 'Page Status' to Draft mode.
