 ## Creating a hotfix branch
+
 Customers in MinIO are allowed LTS on any release they choose to standardize. Production setups seldom change and require maintenance. Hotfix branches are such maintenance branches that allow customers to operate a production cluster without drastic changes to their deployment.
 
 ## Backporting a fix
+
 Developer is advised to clone the MinIO source and checkout the MinIO release tag customer is currently on.

 ```
 λ git checkout RELEASE.2021-04-22T15-44-28Z

 At this point in time the backport is ready to be submitted as a pull request to the relevant branch. A pull request is recommended to ensure [mint](http://github.com/minio/mint) tests are validated. Pull request also ensures code-reviews for the backports incase of any unforeseen regressions.
