   == Configuration
  -The Node.js image offers environment variables that facilitate developing your application.
  +The Node.js image supports a number of environment variables, which can be set
  +to control the configuration and behavior of the Node.js runtime.
   
   To set these environment variables, you can place them into
   link:../../dev_guide/builds.html#environment-files[a *_.s2i/environment_* file]
  
positive.code: |When set to `true`, enables hot deploy and opens the debug port. Additionally, indicates to tooling that the image is in development mode.  Default is `false`.
  
  |`*DEBUG_PORT*`
  |The debug port. Only valid if DEV_MODE is set to true. Default is 5858.
  
  |===
  
  == Hot Deploying
  
  Hot deployment allows you to quickly make and deploy changes to your application
  
negative.code: changes made in your application source code, you must run your built image with
  the `*DEV_MODE=true*` environment variable.
  
  You can set new environment variables when
  link:../../dev_guide/new_app.html#specifying-environment-variables[creating new
  applications], or
  link:../../dev_guide/environment_variables.html#set-environment-variables[updating
  environment variables for existing objects].
  
  [WARNING]
  ====
  Only use the `*DEV_MODE=true*` environment variable while developing or
  debugging. Using this in your production environment is not recommended.
