+OpenStack Capacity is deployed automatically using a service deploy hook
+with the generated kolla-ansible admin credentials, you can override these

-Additionally, you are required to enable a conditional flag to allow
-HAProxy configuration to be templated to controllers during deployment.

-After defining your credentials, You may deploy OpenStack Capacity
+Additionally, you should ensure these credentials have the correct permissions
+for the exporter. After defining your credentials, You may redeploy OpenStack Capacity
 using the ``ansible/deploy-os-capacity-exporter.yml`` Ansible playbook
 via Kayobe.
 
 .. code-block:: console
 
     kayobe playbook run ansible/deploy-os-capacity-exporter.yml
 
-It is required that you re-configure the Prometheus, Grafana and HAProxy
-services following deployment, to do this run the following Kayobe command.
-
-.. code-block:: console
-
-    kayobe overcloud service reconfigure -kt grafana,prometheus,haproxy

 If you notice ``HaproxyServerDown`` or ``HaproxyBackendDown`` prometheus
 alerts after deployment it's likely the os_exporter secrets have not been
 set correctly, double check you have entered the correct authentication
