Storyline 360 interactive process/steps template

Good Afternoon, 

I am very new to using Storyline 360 and would love some assistance! I found exactly the type, look and feel of the interactive (process/step) feature I would like to add to my lesson. It was done by @trinarimmer! I tried going back and finding the original source or article to see if there is a template associated with it. But, no matter how hard I search, I can't seem to locate it. I have attached a screenshot of what it looks like. I have no idea how to create it on my own. Thanks for your assistance!
