The index.php is your home template and is assigned automatically to your home page.

The content that overlays the header image is managed using the page's "Header Text" field. The amount of content here can vary, but make sure to check and updates/changes on mobile devices as well as desktop, to ensure a good user experience.

The homepage sections function the same way as the Subpage Default template and section monklets can be used on either the index or the subpage templates.

If a user lands on your site while a livestream is occurring, a pop up notification will display prompting them to watch the livsetream. You can edit the button text and links by going to Content > Link Lists > Livestream Popup - Links in Shelby CMS. The Name will display as the button text and you can fill in the link to go to wherever you like.
