The tutorial demonstrates how to use Strapi as a Product Information Manager (PIM) to manage products from multiple sources and distribute them across various sales channels. It starts by setting up Strapi and creating a content type for products, then importing data from two different sources - Dummyjson API and Fakestoreapi API. The tutorial shows how to enrich the products with additional data that doesn't exist in the original sources. Next, it sets up a cron job to fetch new products daily and creates a bootstrap function to populate product data into Strapi. The tutorial also covers how to publish products into a custom storefront powered by Nextjs, integrating Strapi's GraphQL API to fetch products and filter featured products for the Hero section. By following this tutorial, users can learn how to build a single source of truth for their products using Strapi as PIM, enabling efficient product management across multiple sales channels.
