Slide-out cart

Site URL: https://www.abbuela.com/

Hi all, 

I am trying to find a template or find the way to customise how people see the product right after added to the cart. I am getting a good amount of add to cart but it seems that people don't know where to click to go to the shopping cart (among other hypothesis). 

I would like to have a slide-out cart (once you add a product to the cart, you can see clearly the product in the cart and proceed to buy directly). Does anyone know how to do it or any template we could use for this? 

Thank you, 

Szilvia
