 The Node Feature Discovery operator manages detection of hardware features and configuration in a kubernetes cluster.
 The operator orchestrates all resources needed to run the [Node-Feature-Discovery](https://github.com/kubernetes-sigs/node-feature-discovery) DaemonSet

-
-## Building the operator
-
-Checkout the sources
-
-```bash
-$ git clone https://github.com/kubernetes-sigs/node-feature-discovery-operator
-```
-
-Build the operator image
-
-```bash
-IMAGE_REGISTRY=<my registry>
-make image
-```
-
-Optionally you can push it to your image repo
-
-```bash
-IMAGE_REGISTRY=<my registry>
-make push
-```
-
-Alternatively, instead of specifying variables on the command line, you can edit the Makefile to permanently change parameter defaults like name of the image or namespace where the operator is deployed.
-
-## Manual deploy of the operator
-
-The default `NodeFeatureDiscovery` CR will create the operand (NFD) in the `node-feature-discovery-operator` namespace,
-also an empty [nfd-worker-conf](https://kubernetes-sigs.github.io/node-feature-discovery/v0.6/get-started/deployment-and-usage.html#configuration),
-the CR can be edited to choose another namespace, image, imagePullPolicy and nfd-worker-conf. See the `manifests/0700_cr.yaml` for the default values.
-
-```bash
-IMAGE_REGISTRY=<my registry>
-make deploy
-```
-
-The operator will use the operand node-feature-discovery image built from: https://github.com/kubernetes-sigs/node-feature-discovery
-
-To uninstall the operator run
-
-```bash
-make undeploy
-```
-
-## Extending Node-feature-discovery with sidecar containers and hooks
-
-First see upstream documentation of the hook feature and how to create a correct hook file:
-
-https://github.com/kubernetes-sigs/node-feature-discovery#local-user-specific-features.
-
-The DaemonSet running on the workers will mount the `hostPath: /etc/kubernetes/node-feature-discovery/source.d`.
-Additional hooks can than be provided by a sidecar container that is as well running on the workers and mounting the same hostpath and writing the hook executable (shell-script, compiled code, ...) to this directory.
-
-NFD will execute any file in this directory, if one needs any configuration for the hook,
-a separate configuration directory can be created under `/etc/kubernetes/node-feature-discovery/source.d`
-e.g. `/etc/kubernetes/node-feature-discovery/source.d/own-hook-conf`, NFD will not recurse deeper into the file hierarchy.

+### Build the operator image

+Alternatively, instead of specifying variables on the command line,
+you can edit the Makefile to permanently change parameter defaults
+like name of the image or namespace where the operator is deployed.
+
+## Manual deploy of the operator
+
+After building the image you can simply run
+
+```bash
+IMAGE_REGISTRY=<my registry>
+make deploy
+```
+
+Then create a NodeFeatureDiscovery CR by running
+
+```bash
+kubectl apply -f config/samples/nfd.kubernetes.io_v1_nodefeaturediscovery.yaml
+```
+
+## Undeploy de operator
+
+The operator will use the operand node-feature-discovery
+image built from: `https://github.com/kubernetes-sigs/node-feature-discovery`
+
+To uninstall the operator run
+
+```bash
+make undeploy
+```
+
+## Clean up labels
+
+In case you need to reomve the labels created by NFD,
+the source Makefile comes with a built in target
+
+```bash
+make clean-labels
+```
+
+This will clean all labels referencing to
+`feature.node.kubernetes.io` and `nfd.node.kubernetes.io`

+# Introduction
+
+The Node Feature Discovery Operator manages the detection
+of hardware features and configuration in an OpenShift
+cluster by labeling the nodes with hardware-specific information.
+The Node Feature Discovery will label the host with
+node-specific attributes,
+like PCI cards, kernel, or OS version, and many more.
+
+Learn about the Node Feature Discovery Operator and
+how you can use it to expose node-level
+information by orchestrating the Node Feature Discovery,
+a Kubernetes add-on for detecting hardware features and system configuration!
