+
+## TL;DR
+```console
+$ helm repo add k8s-at-home https://k8s-at-home.com/charts/
+$ helm install k8s-at-home/statping
+```
+
+## Installing the Chart
+To install the chart with the release name `statping`:
+```console
+helm install statping k8s-at-home/statping
+```
+
+## Uninstalling the Chart
+To uninstall the `statping` deployment:
+```console
+helm uninstall statping
+```
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+Read through the [values.yaml](https://github.com/k8s-at-home/charts/blob/master/charts/statping/values.yaml)
+file. It has several commented out suggested values.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+```console
+helm install statping \
+  --set statping.env.TZ="America/New York" \
+    k8s-at-home/statping
+```
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the
+chart. For example,
+```console
+helm install statping k8s-at-home/statping --values values.yaml 
+```
+
