+## Port Forwarding
+
+Sometimes you need to access a service or pod directly from your local machine. Use the following command to forward a port:
+
+```bash
+kubectl port-forward -n <namespace-name> svc/<service-name> <local-port>:<target-port>
+```
+
+> **Example:** Forward local port 8080 to port 80 of the service named `my-service` in the `mynamespace` namespace:
+>
+> ```bash
+> kubectl port-forward -n mynamespace svc/my-service 8080:80
+> ```
