-For the controller, the `-kubeconfig` and `-config-ns` command-line flags
+For the controller, the `-kubeconfig` and `-namespace` command-line flags
are needed. Speakers need those and `-node-name`.
For example:
```bash
-metallb$ go run ./controller/main.go ./controller/service.go -config-ns metallb-system -kubeconfig $KUBECONFIG
+metallb$ go run ./controller/main.go ./controller/service.go -namespace metallb-system -kubeconfig $KUBECONFIG
-metallb$ go run ./speaker/main.go ./speaker/*controller.go -config-ns metallb-system -kubeconfig $KUBECONFIG -node-name node0
+metallb$ go run ./speaker/main.go ./speaker/*controller.go -namespace metallb-system -kubeconfig $KUBECONFIG -node-name node0
```
