-### Steps to install and configure NFD operator on OCP Cluster.
-
-1. [NFD operator](https://github.com/openshift/cluster-nfd-operator) is used to manage the NFD stack. So firstly follow [NFD operator installation instructions](https://docs.openshift.com/container-platform/4.12/hardware_enablement/psap-node-feature-discovery-operator.html#install-operator-web-console_node-feature-discovery-operator) to install NFD operator on the OCP cluster. 
+1. Follow the [NFD operator installation instructions](https://docs.openshift.com/container-platform/4.12/hardware_enablement/psap-node-feature-discovery-operator.html#install-operator-web-console_node-feature-discovery-operator) to install the NFD operator. 
 
 2. Create NodeFeatureDiscovery instance
 
-```$ oc apply -f https://github.com/intel/intel-technology-enabling-for-openshift/blob/main/nfd/node-feature-discovery-openshift.yaml```
+   ```$ oc apply -f https://github.com/intel/intel-technology-enabling-for-openshift/blob/main/nfd/node-feature-discovery-openshift.yaml```
 
 3. Create NodeFeatureRule instance
 
-```$ oc apply -f https://github.com/intel/intel-technology-enabling-for-openshift/blob/main/nfd/node-feature-rules-openshift.yaml```
+   ```$ oc apply -f https://github.com/intel/intel-technology-enabling-for-openshift/blob/main/nfd/node-feature-rules-openshift.yaml```
+
+4. If NFD has been configured properly, NFD will detect and label Intel® hardware features present on each node in the cluster.
