-[Dispatch Workers](/cloudflare-for-platforms/workers-for-platforms/reference/how-workers-for-platforms-works/#dynamic-dispatch-worker) are used to execute user Workers from the dispatch namespace. You will now create a dispatch Worker and add logic it needs to route to the user Worker created in step 2.
+A [dynamic dispatch Worker](/cloudflare-for-platforms/workers-for-platforms/reference/how-workers-for-platforms-works/#dynamic-dispatch-worker) is a specialized routing Worker that directs incoming requests to the appropriate user Workers in your dispatch namespace. Instead of using traditional route mappings, dispatch Workers let you programmatically control request routing through code.
+
+#### Why use a dynamic dispatch Worker?
+
+* **Scale**: Perfect for routing thousands or millions of hostnames to different Workers, without needing to rely on [Workers Routes](https://developers.cloudflare.com/workers/configuration/routing/routes/)
+* **Custom routing logic**: Write code to determine exactly how requests should be routed. For example:
+   * Map hostnames directly to specific Workers
+   * Route requests based on subdomains
+   * Use request metadata or headers for routing decisions
+
+* **Add platform functionality**: Build in additional features at the routing layer:
+   * Run authentication checks before requests reach user Workers
+   * Sanitize incoming requests
+   * Attach useful context like user IDs or account information
+   * Transform requests or responses as needed
+
+**To create your dynamic dispatch Worker:**
 
 Navigate up a level from your user Worker's project directory:
 
 ```sh
 cd ..
 ```
