-# Send requests using Istio Egress
+# Send Requests Using Istio Egress Gateway
+Learn how to configure and use the Istio egress Gateway to allow outbound traffic from your Kyma runtime cluster to specific external destinations. Test your configuration by sending an HTTPS request to an external website using a sample Deployment.
 
 ## Prerequisites
 
-* Istio module with egress enabled.
+* You have the Istio module added.
 * To use CLI instruction, you must install [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl)
