+Create the licensing Secret for NLS Token
+==========================================
 
 Prerequisites

-Generate and download a NLS client license token. See Section 4.6 of the `NVIDIA License System User Guide <https://docs.nvidia.com/license-system/latest/pdf/nvidia-license-system-user-guide.pdf>`_ for instructions.
+#. Generate and download a NLS client license token. See Section 4.6 of the `NVIDIA License System User Guide <https://docs.nvidia.com/license-system/latest/pdf/nvidia-license-system-user-guide.pdf>`_ for instructions.
+Save the token to a file named ``client_configuration_token.tok``.
+
+#. Create an empty ``gridd.conf`` file.
 
 Procedure
 ---------
 
+Create a licensing secret in the ``nvidia-gpu-operator`` namespace via CLI:
+
+.. code-block:: console
+
+   $ oc create secret generic licensing-config \
+       -n nvidia-gpu-operator --from-file=gridd.conf --from-file=client_configuration_token.tok
+
+Alternatively, you can create the secret using the OpenShift web console:
+
 #. Navigate to **Home** > **Projects** and ensure the ``nvidia-gpu-operator`` is selected.
 
 #. Select the **Workloads** Drop Down menu.
 
-#. Select **ConfigMaps** and then click **Create ConfigMap**.
+#. Select **Secrets** and then click **Create**/ > **Key/value secret**.
 
-#. On the **Create ConfigMap** window, click **YAML view**.
-
-#. Enter the details for your config map.
+#. Enter the details for your secret.
 
    #. The ``name`` must be ``licensing-config``.
 
-   #. Copy and paste the information for your NLS client token into the ``client_configuration_token.tok`` parameter.
+   #. Upload the two files as keys:
+
+      * ``client_configuration_token.tok``
+      * ``gridd.conf``

+.. note::
+
+   Using a Kubernetes Secret to store licensing information is the recommended approach.
+   The ``configMap`` option is deprecated and will be removed in a future release.
