# Federation Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) *Federation feature is deprecated and should be avoided for future deployments*

This document explains how to configure MinIO with `Bucket lookup from DNS` style federation.

## Get started

### 1. Prerequisites

Install MinIO - [MinIO Quickstart Guide](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html).

Tienes que dejarlo allí por un tiempo porque hay clientes usándolo, pero quieres que la documentación lo muestre claramente como <abbr title="obsoleto, se recomienda no usarlo">deprecated</abbr>.

Luego pasa el parámetro `deprecated=True` a `Query`:

{* ../../docs_src/query_params_str_validations/tutorial010_an_py310.py hl[19] *}

La documentación lo mostrará así:
