 Here is an example of how to patch the `status` subresource for a CRD object using `kubectl`:
 ```bash
 kubectl patch customresourcedefinitions <CRD_Name> --subresource='status' --type='merge' -p '{"status":{"storedVersions":["v1"]}}'

 The flag `--subresource=[subresource-name]` is used with kubectl commands like get, patch,
-edit and replace to fetch and update `status` and `scale` subresources of the resources
-(applicable for kubectl version v1.24 or more). This flag is used with all the API resources
-(built-in and CRs) that have `status` or `scale` subresource. Deployment is one of the
-examples which supports these subresources.

+resources you specify. You can specify a subresource for any of the Kubernetes API resources
+(built-in and CRs) that have `status`, `scale` or `resize` subresource.
+
+For example, a Deployment has a `status` subresource and a `scale` subresource, so you can
+use `kubectl` to get or modify just the `status` subresource of a Deployment.
