## What it is
The Registry is a stateless, highly scalable server side application that stores
and lets you distribute Docker images. The Registry is open-source, under the
permissive [Apache license](http://en.wikipedia.org/wiki/Apache_License).
## Why use it
You should use the Registry if you want to:
* tightly control where your images are being stored
* fully own your images distribution pipeline
* integrate image storage and distribution tightly into your in-house development workflow
## Alternatives
Users looking for a zero maintenance, ready-to-go solution are encouraged to
head-over to the [Docker Hub](https://hub.docker.com), which provides a
free-to-use, hosted Registry, plus additional features (organization accounts,
automated builds, and more).
Users looking for a commercially supported version of the Registry should look
into [Docker Trusted Registry](/docker-trusted-registry/overview/).
## Requirements
The Registry is compatible with Docker engine **version 1.6.0 or higher**. If
you really need to work with older Docker versions, you should look into the
[old python registry](https://github.com/docker/docker-registry).
## TL;DR
Start your registry
docker run -d -p 5000:5000 --name registry registry:2
Pull (or build) some image from the hub
docker pull ubuntu
Tag the image so that it points to your registry
docker tag ubuntu localhost:5000/myfirstimage
Push it
docker push localhost:5000/myfirstimage
Pull it back
docker pull localhost:5000/myfirstimage
Now stop your registry and remove all data
docker stop registry && docker rm -v registry
## Next
You should now read the [detailed introduction about the
registry](introduction.md), or jump directly to [deployment
instructions](deploying.md).
