First you need to create a presentation with Google Slides.
Don’t know how to do it? Here the official Google guide.
After you have created the presentation, click on File (1) and then Publish to the web (2).
In the pop-up that appears to you, in the Auto-advance slides field (1) you can decide how long each individual slide should be displayed.
We also recommend that you select both of the checkboxes below: Start slideshow as soon as the player loads and Restart the slideshow after the last slide (2).
After that, click on Publish (3).
Now you just have to copy the link that is generated by Google.
At this point, open the configuration page of your instantPlay Web.
In the Signage Settings section, paste the link into the Web resource’s URL (1).
Finally, click on Save (2) and while the countdown appears close the tab to return to monitor the content just loaded.
That’s the final result.
