-## Minimal
+## Default
 
 This is a minimal image based on
 [gcr.io/distroless/base](https://github.com/GoogleContainerTools/distroless/blob/master/base/README.md)
-and only supports running statically linked binaries.
 
 For backwards compatibility a container image tag with suffix `-minimal`
 (e.g. `{{ site.container_image }}-minimal`) is provided.
 
 ## Full
 
 This image is based on [debian:bullseye-slim](https://hub.docker.com/_/debian)
-and contains a full Linux system for running shell-based nfd-worker hooks and
-doing live debugging and diagnosis of the NFD-Operator images.
-
 The container image tag has suffix `-full`
-(e.g. `{{ site.container_image }}-full`).

+## Uninstallation
+
+If you followed the deployment instructions from the [Quick start](index) you
+can simply do:
+
+```bash
+kubectl -n nfd-operator delete NodeFeatureDiscovery my-nfd-deployment
+```
+
+Optionally, you can also remove the namespace:
+
+```bash
+kubectl delete ns nfd-operator
+```
+
+See the [node-feature-discovery-operator][nfd-operator] and [OLM][OLM] project
+documentation for instructions for uninstalling the operator and operator
+lifecycle manager, respectively.
+
+## 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.
+
+```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).
