# Registry

## Introduction

A Registry is a hosted service containing
[*repositories*](../repository/#repository-def) of
[*images*](../image/#image-def) which responds to the Registry API.

The default registry can be accessed using a browser at
[http://images.docker.io](http://images.docker.io) or using the
`sudo docker search` command.
