+# node-feature-discovery helm chart
+
+This is a helm chart for [node-feature-discovery](https://github.com/kubernetes-sigs/node-feature-discovery) using the master/worker pattern.
+
+## TL;DR
+
+```shell
+helm repo add billimek https://billimek.com/billimek-charts/
+helm install billimek/node-feature-discovery
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```shell
+helm install my-release billimek/node-feature-discovery
+```
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```shell
+helm delete my-release --purge
+```
+
+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 Sentry chart and their default values.
+Read through the [values.yaml](https://github.com/billimek/billimek-charts/blob/master/charts/node-feature-discovery/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 my-release \
+  --set image.pullPolicy="Always" \
+    billimek/node-feature-discovery
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
+
+```console
+helm install my-release -f values.yaml billimek/node-feature-discovery
+```
