 :keywords: amazon ec2, virtualization, cloud, docker, documentation, installation
 
-Using Vagrant (Amazon EC2)
-==========================
+Amazon EC2
+==========
 
-This page explains how to setup and run an Amazon EC2 instance from
-your local machine.  **Vagrant is not necessary to run Docker on
-EC2.** You can follow the :ref:`ubuntu_linux` instructions installing
-Docker on any EC2 instance running Ubuntu.

-Installation
-------------
+There are several ways to install Docker on AWS EC2:
 
-.. include:: install_header.inc
+* :ref:`amazonquickstart` or
+* :ref:`amazonstandard` or
+* :ref:`amazonvagrant`
+
+**You'll need an** `AWS account <http://aws.amazon.com/>`_ **first, of course.**
+
+.. _amazonquickstart:
+
+Amazon QuickStart
+-----------------
+
+1. **Choose an image:**
+
+   * Open http://cloud-images.ubuntu.com/locator/ec2/
+   * Enter ``amd64 precise`` in the search field (it will search as you
+     type)
+   * Pick an image by clicking on the image name. *An EBS-enabled
+     image will let you t1.micro instance.* Clicking on the image name
+     will take you to your AWS Console.
+
+2. **Tell CloudInit to install Docker:**
+
+   * Enter ``#include https://get.docker.io`` into the instance *User
+     Data*. `CloudInit <https://help.ubuntu.com/community/CloudInit>`_
+     is part of the Ubuntu image you chose and it bootstraps from this
+     *User Data*.
+
+3. After a few more standard choices where defaults are probably ok, your
+   AWS Ubuntu instance with Docker should be running!
+
+**If this is your first AWS instance, you may need to set up your
+Security Group to allow SSH.** By default all incoming ports to your
+new instance will be blocked by the AWS Security Group, so you might
+just get timeouts when you try to connect.
+
+Installing with ``get.docker.io`` (as above) will create a service
+named ``dockerd``. You may want to set up a :ref:`docker group
+<dockergroup>` and add the *ubuntu* user to it so that you don't have
+to use ``sudo`` for every Docker command.
+
+Once you've got Docker installed, you're ready to try it out -- head
+on over to the :doc:`../use/basics` or :doc:`../examples/index` section.
+
+.. _amazonstandard:
+
+Standard Ubuntu Installation
+----------------------------
+
+If you want a more hands-on installation, then you can follow the
+:ref:`ubuntu_linux` instructions installing Docker on any EC2 instance
+running Ubuntu. Just follow Step 1 from :ref:`amazonquickstart` to
+pick an image (or use one of your own) and skip the step with the
+*User Data*. Then continue with the :ref:`ubuntu_linux` instructions.
