Deep Theme comes with Slider Revolution and a number of demos to make your life easier.
To import a slider, go to WordPress Dashboard > Slider Revolution, click on Import Slider and then a pop-up window will be open.
In the new window, select your preferred slider file for a demo, then click on “Import Slider” and wait until the import is complete.
You may face an error from Slider Revolution while the slider is completely imported in Front-End. There is nothing to be worried about, go to the page backend and set the slider again.
