Seeking tutorial for Varbase Vartheme Hero Slider

Hello,

I just installed Drupal 8 using the Varbase package. I somehow got the home page Hero slider to work, but I really want to develop it better. This means embedding html elements in each slide, which I seem not to be able to do. I have a lot of experience with Revolution Slider in WordPress, so I know what I want to do. I just don’t know how to do it with the Hero slide show that comes with Varbase.

What I really need is instruction and tutorials for the Varbase Hero slide show program.

Drupal version:
