 ## Adjust your overcloud:
 
 To modify the number of workers each service is running:
 ```
-# ansible-playbook -i hosts browbeat/adjustment.yml -e "workers=8"
+# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8"
 ```
 Nova and Keystone will be running 8 workers per service.
 
 To modify number of workers each service is running and ensure Keystone is deployed in eventlet:
 ```
-# ansible-playbook -i hosts browbeat/adjustment.yml -e "workers=8 keystone_deployment=eventlet"
+# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=eventlet"

 To run Keystone in httpd, change keystone_deployment to httpd:

+# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=httpd"
