How to activate Slider Revolution?

You don't need to activate any plugins included in the theme. All bundled plugins (including Revolution Slider) are already fully functional. Check this article for more details on bundled plugins.

All of the plugins included and required / recommended in our theme are being regularly updated via our own plugin repository.  Please note: for ensuring the highest quality of working as well as full compatibility we release the updates of the plugins only after checking it on possible compatibility issues with our theme.
