-## Grafana
-
-Deis Workflow exposes Grafana through the router using [service annotations](https://github.com/deis/router#how-it-works). This
-allows users to access the Grafana UI at `http://grafana.mydomain.com`. The default username/password of
-`admin/admin` can be overridden at Workflow chart install time by modifying the appropriate values under the `monitor` section in Workflow's global [values.yaml](https://github.com/deis/workflow/blob/master/charts/workflow/values.yaml) or via `--set`:
-
-```
-helm install <workflow repo>/workflow --namespace deis \
-  --set monitor.grafana.user=$GRAFANA_USER,monitor.grafana.password=$GRAFANA_PASSWORD
-```
+## [Grafana](https://grafana.com/)
+Grafana allows users to create custom dashboards that visualize the data captured to the running InfluxDB component. By default Grafana is exposed using a [service annotation](https://github.com/deis/router#how-it-works) through the router at the following URL: `http://grafana.mydomain.com`. The default login is `admin/admin`. If you are interested in changing these values please see [Tuning Component Settings][].
 
 Grafana will preload several dashboards to help operators get started with monitoring Kubernetes and Deis Workflow.
 These dashboards are meant as starting points and don't include every item that might be desirable to monitor in a
 production installation.
 
 Deis Workflow monitoring by default does not write data to the host filesystem or to long-term storage. If the Grafana instance fails, modified dashboards are lost.
 
+### Production Configuration
+A production install of Grafana should have the following configuration values changed if possible:
+
+* Change the default username and password from `admin/admin`. The value for the password is passed in plain text so it is best to set this value on the command line instead of checking it into version control.
+* Enable persistence
+* Use a supported external database such as mysql or postgres. You can find more information [here](https://github.com/deis/monitor/blob/master/grafana/rootfs/usr/share/grafana/grafana.ini.tpl#L62)
+
+
 ### On Cluster Persistence
+Enabling persistence will allow your custom configuration to persist across pod restarts. This means that the default sqllite database (which stores things like sessions and user data) will not disappear if you upgrade the Workflow installation. 
 
 If you wish to have persistence for Grafana you can set `enabled` to `true` in the `values.yaml` file before running `helm install`.
