How to show review stars under all products.

I enabled reviews on our site at https://www.vapesocietysupply.net however I am unable to figure out how to add the stars directly under the product title on home/shop pages.

Is there a way to enable to stars to show underneath all the products?

I tried the suggestions here: https://stackoverflow.com/questions/14227121/how-do-you-add-the-star-ratings-for-products-in-woocommerce

But was unsuccessful. What do I do?
