 DESCRIPTION
-  Starts a local HTTP proxy that injects Salesforce authentication and routes
-  requests between your dev server and Salesforce APIs. In command mode,
-  spawns and monitors the dev server (default URL: localhost:5173). In
-  URL-only mode, connects to an already-running dev server.
+  Preview a web app locally without needing to deploy
+
+  Starts a local development server for a Web Application, using the local project files. This enables rapid
+  development with hot reloading and immediate feedback.
 
 EXAMPLES
-  Command mode (CLI starts dev server, default port 5173):
+  Start the development server:
 
-    $ sf ui-bundle dev --name myapp --target-org myorg --open
+    $ sf webapp dev --name myWebApp
 
-  URL-only mode (dev server already running):
+  Start the development server with a specific target:
 
-    $ sf ui-bundle dev --name myapp --target-org myorg --url http://localhost:5173 --open
+    $ sf webapp dev --name myWebApp --target "LightningApp"
 
-  Custom proxy port:
+  Start the development server on a custom port:
 
-    $ sf ui-bundle dev --name myapp --target-org myorg --port 8080 --open
+    $ sf webapp dev --name myWebApp --port 8080
