  +This tutorial walks you through creating and deploying a dev release and then
  +a final release.
  +
  +More than one dev release is typically required before you are ready to do a
  +final release.
  +For that reason, the tutorial is designed so that you can prepare once (by
  +completing the material in this section), then iterate through
  +the material about dev releases (Steps 1 through 6) as many times as necessary
  +before proceeding to do a final release.

   When you deploy a release, BOSH creates two kinds of VMs on the target IaaS:
   
  
positive.code: fundamental elements: jobs, packages, source (which BOSH calls `src`), and
  blobs.

  View the release with `tree`:
  
  
negative.code: The workflow for creating BOSH releases is iterative, and looks like this:
