Very Confusing. Unsure of how to Operate

So I hate to be that guy and give a 1 star. But when it comes to this plugin. I have had trouble getting it set up. I was very confused by the instructions and hate to say this, but I will have to find an alternative method to show Yelp Reviews.

I have not been able to find a video review for this plugin when I did the “View Details” and tried working on this for almost a half hour. I hate to give this 1-star, but I need to be honest.
