  Create a deployments directory with a subdirectory for your
  particular deployment. For example, `~/deployments/cf-example`. In
  the particular deployment's sub-directory, create a file named `Gemfile` with the following contents:
  
  ~~~
  source 'https://rubygems.org'
  
negative.code: ~/deployments/cf-example$ source bosh_environment
  </pre>
  
  Run the `bosh aws create` command to generate the receipt files that you use
  when deploying software with BOSH (`aws_rds_receipt.yml` and `aws_vpc_receipt.yml`).
  `bosh aws create` also creates a VPC Internet Gateway, VPC subnets,
  three RDS databases, and a NAT VM.
  The NAT VM is for use with Cloud Foundry.
  You can remove it if you plan to deploy software other than Cloud Foundry.
  
  `bosh aws create` takes some time but does not require user input.

  ~/cf$ bundle exec bosh aws create
