+#### Minio Configuration
+
+To use S3 storage with Athens, set `storage.type` to `minio`. You need to set `storage.minio.endpoint` as the URL of your minio-installation.
+This URL can also be an kubernetes-internal one (e.g. something like `minio-service.default.svc`).
+You need to create a bucket inside your minio-installation or use an existing one. The bucket needs to be referenced in `storage.minio.bucket`.
+Last athens need authentication credentials for your minio in `storage.minio.accessKey` and `storage.minio.secretKey`.
+
+```
+helm install gomods/athens-proxy -n athens --namespace athens --set storage.type=minio --set storage.minio.endpoint=<your-minio-endpoint> --set storage.minio.bucket=<your-bucket> --set storage.minio.accessKey=<your-minio-access-key> --set storage.minio.secretKey=<your-minio-secret-key>
+```

 ### Kubernetes Service
 
 By default, a Kubernetes `ClusterIP` service is created for the Athens proxy. "ClusterIP" is sufficient in the case when the Athens proxy will be used from within the cluster. To expose Athens outside of the cluster, consider using a "NodePort" or "LoadBalancer" service. This can be changed by setting the `service.type` value when installing the chart. For example, to deploy Athens using a NodePort service, the following command could be used:
