Hello there,
Thank you for using our theme and contacting us.
All you need to do is to open admin panel, go to pages, find your home page and click edit. There you will see Visual Composer interface where you can add Revolution Slider as it’s element. (if you don’t see it then go to Visual Composer -> Role Manager ->
Post types -> “Custom” and check all post types you need including HTML Blocks)
Here are some videos about Visual Composer usage https://vc.wpbakery.com/video-tutorials/
Kind Regards
