After the customer adds an item to their cart, how do they view their cart and check out?

I have the store basically set up, using Stripe as my payment gateway. When someone adds a product to the cart, it just refreshes the page. I get that this is so they can continue shopping, but I need there to be a visible way for them to "go to their cart" and complete checkout if they are done shopping. I have the Cart page as a dropdown under my store in the nav menu, but that's not too intuitive. Is there a way to make a "view my cart" button appear once the customer has added something to the cart? Thanks!
