## 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](https://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).
## Requirements
The Registry is compatible with Docker engine **version 1.6.0 or higher**.
## Basic commands
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 image 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 container stop registry && docker container rm -v registry
## Next
You should now read the [detailed introduction about the registry](introduction.md),
or jump directly to [deployment instructions](deploying.md).
