Slider Question

First of all, amazing job on the theme!

However, I can’t seem to figure out how the slider works with this theme. I want 3-4 slides of different clickable images on my home page. I have the Great: Slider widget enabled on a particular cell on my home page [Shown here]

Keep in mind I am a beginner so all the help is appreciated.
