# Introduction

This document outlines how to make hotfix binaries and containers for MinIO?. The main focus in this article is about how to backport patches to a specific branch and finally building binaries/containers.

## Pre-pre requisite

- A working knowledge of MinIO codebase and its various components.
- A working knowledge of AWS S3 API behaviors and corner cases.

## Pre-requisite for backporting any fixes

```sh
./prometheus --help
usage: prometheus [<flags>]

## Introduction

To integrate with custom authentication methods using the [Identity Management Plugin](../iam/identity-management-plugin.md)), MinIO provides an STS API extension called `AssumeRoleWithCustomToken`.

After configuring the plugin, use the generated Role ARN with `AssumeRoleWithCustomToken` to get temporary credentials to access object storage.

## Introduction

MinIO provides a custom STS API that allows authentication with client X.509 / TLS certificates.

# AssumeRoleWithClientGrants [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

## Introduction

Returns a set of temporary security credentials for applications/clients who have been authenticated through client credential grants provided by identity provider. Example providers include KeyCloak, Okta etc.

# AssumeRole [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

## Introduction

Returns a set of temporary security credentials that you can use to access MinIO resources. AssumeRole requires authorization credentials for an existing user on MinIO. The advantages of this API are
