+# Removing feature labels
+
+From the [Operand repository][nfd] NFD-Master has a special `-prune` command
+line flag for removing all nfd-related node labels, annotations and extended
+resources from the cluster.
+
+In order to remove all feature labels from the cluster, run the following
+command:
+
+```bash
+kubectl apply -k https://github.com/kubernetes-sigs/node-feature-discovery/deployment/overlays/prune?ref={{ site.release }}
+kubectl -n node-feature-discovery wait job.batch/nfd-master --for=condition=complete && \
+    kubectl delete -k https://github.com/kubernetes-sigs/node-feature-discovery/deployment/overlays/prune?ref={{ site.release }}
+```
+
+**NOTE:** You must run prune before removing the RBAC rules (serviceaccount,
+clusterrole and clusterrolebinding).
