Plugin Isn’t Working

Hello,

I downloaded the plugin and added it to the widget sidebar. But, the website doesn’t use the sidebar on any of the pages. The resizer doesn’t show up anywhere on the front end when I have it activated and in the sidebar widget. How do I add this resizer if I don’t use the sidebar on the website? Is there a shortcode I can add to the front page of the website? I read through the support topics and saw something about Github and I clicked on that, but I have no idea what any of that means. Thank you.
