+A [deployed application]({{< ref deploy-apps >}}) in a Radius environment.
+
+## How-to: Delete a  application
+
+1. You can delete a Radius application from the environment using the [`rad app delete`]({{< ref rad_application_delete >}}) command.
+
+    ```bash
+    rad app delete app.bicep
+    ```
+
+    This will delete the following resources from the default Radius environment
+
+    1. All the resources created by Radius on the Kubernetes cluster under the 'default-<appname>' namespace
+    2. All the resources provisioned by Recipes
+
+    This will not delete the following resources from the default Radius environment
+
+    1. Any resources already provisioned by the user outside of Radius (e.g. manually created resources)
+    2. Any cloud/platform resources provisioned by Radius (e.g. Azure/AWS/Kubernetes resources)
+
+
+2. Delete the Cloud/Platform resources
+
+    To avoid incurring costs, please make sure to manually delete the cloud/platform resources provisioned by Radius.
