## Overview ## Overview
Docker Stacks and Distributed Application Bundles are experimental features
introduced in Docker 1.12 and Docker Compose 1.8, alongside the concept of
swarm mode, and Nodes and Services in the Engine API.

nor the Docker Registry support distribution of bundles, and the concept of a
`bundle` is not the emphasis for new releases going forward.
However, [swarm mode](/engine/swarm/index.md), multi-service applications, and
stack files now are fully supported. A stack file is a particular type of
[version 3 Compose file](/compose/compose-file/index.md).
If you are just getting started with Docker and want to learn the best way to
deploy multi-service applications, a good place to start is the [Sample app
tutorial](/engine/getstarted-voting-app/index.md). This shows you how to define
a service configuration in a `docker-stack.yml` file, deploy the app, and use
the relevant tools and commands.
