+kubernetes-sigs/node-feature-discovery
+======================================
+
+This chart runs v0.3.0 of the node-feature-discovery as implemented
+at https://github.com/kubernetes-sigs/node-feature-discovery
+
+This software enables node feature discovery for Kubernetes. It detects
+hardware features available on each node in a Kubernetes cluster, and
+advertises those features using node labels.
+
+This chart uses a DaemonSet to spawn a pod on each node in the cluster
+to do the actual work.
+
+The two files under the templates directory are taken directly from
+v0.3.0 at the link above.  The Docker image specified is the one
+published by the upstream team.
