+# About Docker Engine
+
+**Develop, Ship and Run Any Application, Anywhere**
+
+[**Docker**](https://www.docker.com) is a platform for developers and sysadmins
+to develop, ship, and run applications.  Docker lets you quickly assemble
+applications from components and eliminates the friction that can come when
+shipping code. Docker lets you get your code tested and deployed into production
+as fast as possible.
+
+Docker consists of:
+
+* The Docker Engine - our lightweight and powerful open source containerization
+  technology combined with a work flow for building and containerizing your
+  applications.
+* [Docker Hub](https://hub.docker.com) - our SaaS service for
+  sharing and managing your application stacks.
+
+## Why Docker?
+
+*Faster delivery of your applications*
+
+* We want your environment to work better. Docker containers,
+      and the work flow that comes with them, help your developers,
+      sysadmins, QA folks, and release engineers work together to get your code
+      into production and make it useful. We've created a standard
+      container format that lets developers care about their applications
+      inside containers while sysadmins and operators can work on running the
+      container in your deployment. This separation of duties streamlines and
+      simplifies the management and deployment of code.
+* We make it easy to build new containers, enable rapid iteration of
+      your applications, and increase the visibility of changes. This
+      helps everyone in your organization understand how an application works
+      and how it is built.
+* Docker containers are lightweight and fast! Containers have
+      sub-second launch times, reducing the cycle
+      time of development, testing, and deployment.
+
+*Deploy and scale more easily*
+
+* Docker containers run (almost) everywhere. You can deploy
+      containers on desktops, physical servers, virtual machines, into
+      data centers, and up to public and private clouds.
+* Since Docker runs on so many platforms, it's easy to move your
+      applications around. You can easily move an application from a
+      testing environment into the cloud and back whenever you need.
+* Docker's lightweight containers also make scaling up and
+      down fast and easy. You can quickly launch more containers when
+      needed and then shut them down easily when they're no longer needed.
+
+*Get higher density and run more workloads*
+
+* Docker containers don't need a hypervisor, so you can pack more of
+      them onto your hosts. This means you get more value out of every
+      server and can potentially reduce what you spend on equipment and
+      licenses.
+
+*Faster deployment makes for easier management*
+
+* As Docker speeds up your work flow, it gets easier to make lots
+      of small changes instead of huge, big bang updates. Smaller
+      changes mean reduced risk and more uptime.

+## About this guide
+
+The [Understanding Docker section](understanding-docker.md) will help you:
+
+ - See how Docker works at a high level
+ - Understand the architecture of Docker
+ - Discover Docker's features;
+ - See how Docker compares to virtual machines
+ - See some common use cases.
+
+### Installation guides
+
+The [installation section](installation/index.md) will show you how to install Docker
+on a variety of platforms.
+
+
+### Docker user guide

+To learn about Docker in more detail and to answer questions about usage and
+implementation, check out the [Docker User Guide](userguide/index.md).
+
+## Release notes
+
+A summary of the changes in each release in the current series can now be found
+on the separate [Release Notes page](https://docs.docker.com/release-notes)
+
+## Feature Deprecation Policy
+
+As changes are made to Docker there may be times when existing features
+will need to be removed or replaced with newer features. Before an existing
+feature is removed it will be labeled as "deprecated" within the documentation
+and will remain in Docker for, usually, at least 2 releases. After that time
+it may be removed.
+
+Users are expected to take note of the list of deprecated features each
+release and plan their migration away from those features, and (if applicable)
+towards the replacement features as soon as possible.
+
+The complete list of deprecated features can be found on the
+[Deprecated Features page](deprecated.md).
