 * Make sure that the WebLogic operator is running.
 * The operator requires WebLogic Server 12.2.1.3.0 with patch 28076014 applied. Refer to [WebLogic Docker images](../../../../../site/weblogic-docker-images.md) for details on how to create one. If a different `domainHomeImageBase` (see Configuration table below) is specified, the specified image needs to be built locally or pulled from a repository.
 * Create a Kubernetes namespace for the domain unless the intention is to use the default namespace.
-* Create the Kubernetes secrets `username` and `password` of the admin account in the same Kubernetes namespace as the domain.
+* Create a Kubernetes secret for the WebLogic administrator credentials that contains the fields `username` and `password`, and make sure that the secret name matches the value specified for `weblogicCredentialsSecretName` (see Configuration table below). For example:
+
+```
+$ cd ./kubernetes/samples/scripts/create-weblogic-domain-credentials
+$ create-weblogic-credentials.sh
+   -u weblogic
+   -p welcome1
+   -d domain1
+   -n default
+   -s domain1-weblogic-credentials
+```
+**NOTE**: Then make sure to configure `weblogicCredentialsSecretName` to be `domain1-weblogic-credentials`.
