 # Minio Usage Examples
 
-By default, the provided Minio instance provisions a minimal set up policies beyond the defaults. However, no service accounts, additional users or buckets are provisioned.
+By default, the provided Minio instance provisions a minimal set up that includes a single bucket named `uds` that is accessible by the `uds` user:
+
+```
+users:
+  - accessKey: uds
+    secretKey: uds-secret
+    policy: readwrite-username-policy
+```
 
 You can port-forward ```kubectl port-forward service/minio 9000:9000 -n uds-dev-stack``` to access the service externally from where you can use any s3 compatible client to configure your buckets or the minio (mc) cli to handle other configurations, users or policy management. Similar functions could be performed in-cluster as well via a Job or other means.
