+#### Injecting Labels from Other Pods
+
+One use case for the hooks and/or feature files is detecting features in other
+Pods outside NFD, e.g. in Kubernetes device plugins. It is possible to mount
+the `source.d` and/or `features.d` directories common with the NFD Pod and
+deploy the custom hooks/features there. NFD will periodically scan the
+directories and run any hooks and read any feature files it finds. The
+[example nfd-worker deployment template](https://github.com/kubernetes-sigs/node-feature-discovery/blob/master/nfd-worker-daemonset.yaml.template#L69)
+contains `hostPath` mounts for `sources.d` and `features.d` directories. By
+using the same mounts in the secondary Pod (e.g. device plugin) you have
+created a shared area for delivering hooks and feature files to NFD.
