+## Run
+
+1. Create ns for deployments:
+```bash
+kubectl create ns nsm-system
+```
+
+2. Apply NSM resources for calico tests:
+
+```bash
+kubectl apply -k https://github.com/networkservicemesh/deployments-k8s/examples/calico/?ref=bbe46ecf104280e96ae3a32d4757149e792f0d11
+```
+
+3. Wait for admission-webhook-k8s:
+
+```bash
+WH=$(kubectl get pods -l app=admission-webhook-k8s -n nsm-system --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}')
+kubectl wait --for=condition=ready --timeout=1m pod ${WH} -n nsm-system
+```
+
+## Cleanup
+
+To free resouces follow the next command:
+
+```bash
+kubectl delete mutatingwebhookconfiguration --all
+kubectl delete ns nsm-system
+```
