I see that you’re enrolled in our WooCommerce 101 course, so I’ll assume that your question pertains to WooCommerce.
When you install and activate WooCommerce for the first time, it automatically creates a handful of pages for you, including a shopping cart page, checkout page, and account page.
The cart page created by WooCommerce should already contain the shortcode: [woocommerce_cart]
You can find and manage the pages WooCommerce created by visiting: WooCommerce > Settings > Advanced > Page Setup
As long as there is a cart page, you should be set! WooCommerce will automatically use that page to display the products your customer has added to their shopping cart.
If there is no cart page, visit the documentation on their website on how to create the required pages again.
Hope this helps!
