Allow your customers to provide reviews for your products with Shopify's free Product Reviews app. For most themes, merchants have to make code changes to connect the app with the theme. Superstore is built with the integration in place, so all you need to do is add the app and enable the theme setting.
Add the app to your store
This integration still requires the Product Reviews app in the Apps admin. To add this app, navigate to the Product Reviews App page and select Add app.
Activate in the theme editor
Go to Customize > Theme settings > Products and select Enable product reviews and ratings.
