 ##### Configure authentication
 The default authentication for the operator is `token`. No further steps are required to configure token authentication. If `basic` is the preferred authentication method, a Secret must be created which holds username and password credentials:
 1. On the left navigation pane, select `Workloads` -> `Secrets` -> select Project: `koku-metrics-operator` -> `Create` -> `Key/Value Secret`
-2. Give the Secret a name and add 2 keys: `username` and `password` (all lowercase). The values for these keys correspond to console.redhat.com credentials.

 3. Select `Create`.
 ##### Create the KokuMetricsConfig

 1. On the left navigation pane, select `Operators` -> `Installed Operators` -> `koku-metrics-operator` -> `KokuMetricsConfig` -> `Create Instance`.
