-Kibana comes preconfigured with a reserved role called `kibana_dashboard_only_user` which will be sufficient
-for most use cases.  However, if your setup requires a custom Kibana index, you can manually create
-Dashboard Mode roles.
+If {security} is enabled, Kibana has a built-in `kibana_dashboard_only_user` 
+role that grants read only access to the `.kibana` index. This role is sufficient
+for most use cases.  However, if your setup requires a custom {kib} index, you can create
+your own roles and tag them as *Dashboard only mode*.
 
-To do so, go into *Management > Advanced Settings* and search for `xpackDashboardMode:roles`. Then assign whatever
-role names you wish to use to flag a user for Dashboard Only mode.
+Go to *Management > Kibana > Advanced Settings* and search for *Dashboard*. By default 
+`xpackDashboardMode:roles` is set to `kibana_dashboard_only_user`. 
+Here you can add as many roles as you like.

-It isn't necessary for Dashboard Only mode roles to have any additional permissions, but it's a convenient location
-to also place access rules to the custom Kibana index. If you wish to grant read only access to your custom Kibana
-index, it must have `view_index_metadata` permissions as well as `read` permissions.  These role settings are available
-under *Management > Security > Roles*.
+By default, a *dashboard only mode* user doesn't have access to any data indices.
+To grant read only access to your custom {kib}
+index, you must assign `view_index_metadata` and `read` privileges.
+These privileges are available under *Management > Security > Roles*.
 
+For more information on roles and privileges, see {xpack-ref}/authorization.html[User Authorization].

 == Kibana Dashboard Only Mode
 
-{xpack} gives the ability for admins to limit what certain users see when they log in to Kibana with a
-reserved `kibana_dashboard_only_user` role.
+If {security} is enabled, you can use the `kibana_dashboard_only_user` built-in role to limit 
+what users see when they log in to {kib}.
 
-When you assign a user this role, the next time they sign in to Kibana they will only be able to see the Dashboard app,
-and no editing tools will be available.

+pane. When users open a dashboard, they will have a limited visual experience. 
+All edit and create controls are hidden.

-IMPORTANT: If a user is also assigned the reserved `superuser` role, they will be able to see all of Kibana and have
-full access.
+To assign this role, go to *Management > Security > Users*, add or edit 
+a user, and add the `kibana_dashboard_only_user` role. You must assign roles 
+that grant the user appropriate data access. For information on roles 
+and privileges, see {xpack-ref}/authorization.html[User Authorization].
+
+The `kibana_dashboard_only_user` role is 
+preconfigured with read only permissions on the `.kibana` index.
+
+IMPORTANT: If you assign users the `kibana_dashboard_only_user` role, along with a role 
+with write permissions on the `.kibana` index, they *will* have write access, 
+even though the controls remain hidden in the {kib} UI.
