+# Weave Cloud Grafana
+
+Grafana v5 with Kubernetes dashboards and Prometheus and Weave Cloud data sources.
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm install stable/grafana --name my-release \
+    --set service.type=NodePort \
+    --set token=WEAVE-TOKEN \
+    --set password=admin
+```
+
+The command deploys Grafana on the Kubernetes cluster in the default namespace.
+The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+$ helm delete --purge my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following tables lists the configurable parameters of the Grafana chart and their default values.
+
+Parameter | Description | Default
+--- | --- | ---
+`image.repository` | Image repository | `grafana/grafana`
+`image.pullPolicy` | Image pull policy | `IfNotPresent`
+`image.tag` | Image tag | `5.0.1`
+`replicaCount` | desired number of pods | `1`
+`resources` | pod resources | `none`
+`tolerations` | List of node taints to tolerate | `[]`
+`affinity` | node/pod affinities | `node`
+`nodeSelector` | node labels for pod assignment | `{}`
+`service.type` | type of service | `LoadBalancer`
+`url` | Prometheus URL, used when Weave token is empty | `http://prometheus:9090`
+`token` | Weave Cloud token | `none`
+`user` | Grafana admin username | `admin`
+`password` | Grafana admin password | `none`
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+$ helm install stable/grafana --name my-release \
+  --set=token=WEAVE-TOKEN \
+  --set password=admin
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```console
+$ helm install stable/grafana --name my-release -f values.yaml
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+```
