No instructions provided on logging in to Grafana UI

Under the monitoring section the docs instruct how to access and enable the Grafana Dashboard. When a user does so and opens the dashboard page in a browser they are presented with a login page:

Our docs do not provide information on obtaining the credentials required to login to the Grafana dashboard. Through some exploration I was able to find the credentials in a monitoring-grafana secret in the mke namespace so they are available, but the docs needs to give guidance here rather than expecting customers to find it on their own.
