 Docker includes swarm mode for natively managing a cluster of Docker Engines called a swarm. You can use the Docker CLI to create a swarm, deploy application services to a swarm, and manage swarm behavior. This tutorial uses [Docker Machine](https://docs.docker.com/machine/) to create multiple nodes on your desktop. If you prefer you can create those nodes in your own cloud or on multiple machines.
 
 >**Important Note**
-You don't need to use the Docker CLI to perform these operations. You can use `docker stack deploy --compose-file STACKNAME.yml STACKNAME` instead. for an introduction to this, check out the [Deploying an app to a Swarm](../beginner/chapters/votingapp.md) for an introduction to using a stack file in a compose file format to deploy an app for more information.
