To clarify the standard and expanded demos is only for X. And for PRO there is what we called Design Cloud. More details about Design Cloud here.
Now with that in mind, we can't really import the Integrity 1 Demo on your PRO site. However, I can import it on my X dev site and send the templates to you.
Integrity 1 Demo Home Page Template
Integrity 1 Demo Theme Options
Download and Import that Integrity 1 Demo Theme Options under Pro > Validation > Theme Options Manager
For the Integrity 1 Demo Home Page Template import that under Pro > Template Manager, and then load that template to your homepage. Keep in mind that we only import the homepage in a standard demo, so please don't look for the other pages .
More details about the Template Manager here.
Import and load the Home Page template and edit it, there are only place-holder text and place-holder images on that template for you to change with your own content.
Now if you want the Slider that is on the top of the page, please read this post.
While editing the page, you might also be confused about the mobile content, please read this post.
Have a nice weekend,
