+#### 5. (Optional) Install Medusa Admin plugin and add product categories
+
+Medusa comes with a few demo products, but they won't show up in the template by default. To showcase products in the store, we need to install the Medusa Admin and add a few product categories:
+
+1. Install the [Medusa Admin plugin](https://docs.medusajs.com/admin/quickstart)
+2. Enable the [Product Categories feature flag](https://docs.medusajs.com/modules/products/categories)
+3. Log in to the admin dashboard and create the following product categories:
+  - hidden-homepage-carousel
+  - hidden-homepage-featured-items
+4. Assign a few products to both categories and they should now show up on the homepage!
