ref(docs/example): create ns in walkthrough
@@ -25,6 +25,10 @@ $ osm install
The `Bookstore`, `Bookbuyer`, `Bookthief`, `Bookwarehouse` demo applications will be installed in their respective Kubernetes Namespaces. In order for these applications to be injected with a Envoy sidecar automatically, we must add the Namespaces to be monitored by the mesh.
```bash
+$ kubectl create ns bookstore
+$ kubect create ns bookbuyer
+$ kubectl create ns bookthief
+$ kubectl create ns bookwarehouse
$ osm namespace add bookstore bookbuyer bookthief bookwarehouse
```
