 # linkerd-viz
-Dead simple monitoring for linkerd
+
+Dead simple monitoring for [linkerd](https://linkerd.io).
+
+![linkerd-viz screenshot](https://linkerd.io/images/dcos/linkerd-viz-screenshot.png "linkerd-viz screenshot")
+
+linkerd-viz is a monitoring application based on
+[Prometheus](https://prometheus.io/) and [Grafana](http://grafana.org/),
+autoconfigured to collect metrics from [linkerd](https://linkerd.io).
+linkerd-viz currently supports [Kubernetes](http://kubernetes.io/) and
+[DC/OS](https://dcos.io/).
+
+linkerd-viz assumes linkerd has already been deployed onto your cluster, and
+your applications have been configured to route via linkerd. For more
+information on getting started with linkerd have a look at our [Getting Started
+guides](https://linkerd.io/getting-started/).
+
+## Build and push Docker image

+
+## Local boot
+
+```bash
+docker run -p 3000:3000 -p 9090:9090 buoyantio/linkerd-viz
+```
+
+## Kubernetes Deploy
+
+```bash
+kubectl apply -f linkerd-viz-k8s.yml
+```
+
+View dashboard
+
+```bash
+open http://$(kubectl get svc linkerd-viz -o jsonpath="{.status.loadBalancer.ingress[0].ip}")
+```
+
+## DC/OS Deploy
+
+```bash
