+## Introduction
+
+[Generic Device Plugin](https://github.com/squat/generic-device-plugin)
+
+The generic-device-plugin enables allocating generic Linux devices, such as serial devices, the FUSE device, or video cameras, to Kubernetes Pods.
+
+This chart bootstraps a [Generic Device Plugin](https://github.com/squat/generic-device-plugin) daemonset on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Prerequisites
+
+- Kubernetes
+- Helm
+
+## Parameters
+
+See the [values files](values.yaml).
