+You can skip this step if your subscription is already registered with the Microsoft.NetworkCloud Resource Provider. Otherwise, proceed with the following steps:
+
+In Azure CLI, enter the following commands:
+
+```azurecli
+az provider register --namespace Microsoft.NetworkCloud
+```
+
+Monitor the registration process. Registration may take up to 10 minutes.
+
+```azurecli
+az provider show -n Microsoft.NetworkCloud -o table
+```
+
+Once registered, you should see the RegistrationState state for the namespace change to Registered.
+
+If you've already registered, you can verify using the `show` command.
