  Ruby 1.9.3 and git (1.8 or later) are prerequisites for the following
  steps. After you install Ruby and git, install the `bundler` RubyGem:
  
  <pre class="terminal">
  $ gem install bundler
  </pre>
  
  Create a directory for your planned deployment.
  In that directory:
  
  1. Create a file named `Gemfile` with the following contents:
  
  ~~~
  source 'https://rubygems.org'
  
  ruby "1.9.3"
  
  gem "bosh_cli_plugin_aws"
  ~~~
  
  1. Run the `bundle install` command.
  
  
  Next, set environment variables required for deploying to AWS. Create
  a file called `bosh_environment` and add the following, changing the
  
negative.code: 
  ### <a id='aws'></a> AWS ###
  
  For AWS, there are special BOSH CLI commands to set up your infrastructure.
  This section explains how to install the plugin that provides the commands,
  and then use the commands.
  
  #### <a id='plugin'></a> Install the AWS plugin to the BOSH CLI ####
  
  Ensure that you Ruby 1.9.3 and git (1.8 or later) installed.
  Then install the `bundler` RubyGem:
  
  <pre class="terminal">
  $ gem install bundler
  </pre>
  
  Create a directory for your planned deployment.
  In that directory:
  
  1. Create a file named `Gemfile` with the following contents:
  
  ~~~
  source 'https://rubygems.org'
  
  ruby "1.9.3"
  
  gem "bosh_cli_plugin_aws"
  ~~~
  
  1. Run the `bundle install` command.
  
  #### <a id='domain-prep'></a> Prepare a Domain ####
  
  First, pick a DNS domain name for the environment you plan to deploy.
  If you pick *cloud.mydomain.com*, your applications become available as
  *app-name.cloud.mydomain.com*.
  
  Create an AWS Route 53 Hosted Zone for your domain at the
