 = Deleting a machine pool
 
 You can delete a machine pool in the event that your workload requirements have changed and your current machine pools no longer meet your needs.
-// Over time, users may find that their workload needs have changed, and may want to modify the various machine pool settings. While many of these settings can be modified, certain settings (for example, instance types and availability zones) cannot be changed once a machine pool is created. If a user finds that these settings are no longer meeting their needs, they can delete the machine pool in question and create a new machine pool with the desired settings.
