How OWL Carousel Works:
Whale OWL Carousel comes with a dashboard carousel generator that makes it extremely easy to use for site admins. You can create your carousel at the dashboard, save that and then use it as a ready-to-go carousel on every page you want. These are steps to use this add-on:
1- After installing the add-on you can see an "OWL Carousel" link in the "Files" box of your dashboard.
2- Click on the link, and you will see a list of sliders has already made, so users can check and use them as starting points.
3- Go to the page you intend to add your carousel, select "OWL Carousel" block, select a prebuilt carousel and you are done.
