# Distributed Server Design Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

This document explains the design, architecture and advanced use cases of the MinIO distributed server.

## Command-line

```
NAME:
  minio server - start object storage server

USAGE:
  minio server [FLAGS] DIR1 [DIR2..]
  minio server [FLAGS] DIR{1...64}
  minio server [FLAGS] DIR{1...64} DIR{65...128}

DIR:

configuration itself can no longer be stored in the MinIO config file and
instead must be provided via environment variables. If you have set your KMS
configuration using e.g. the `mc admin config` commands you will need to adjust
your deployment.

Even though this change is backward compatible we do not expect that it affects
the vast majority of deployments in any negative way.
