  The following should get you started on setting up your development environment. As a prerequisite you will need a Ruby 2.2 environment. We
  recommend to use https://rvm.io/[RVM] to create an isolated development
  environment. On Windows the http://rubyinstaller.org/[RubyInstaller for
  Windows] is probably the easiest way to get started. In this case you
  will need the http://rubyinstaller.org/add-ons/devkit/[DevKit] as well.

  Once you have a working Ruby environment it is time to
  https://help.github.com/articles/fork-a-repo/[fork] the repository. Refer to the link:../CONTRIBUTING.adoc[Contributing] guide for more information.
  
  The following sections list the most important commands you will need for
  development.
  
  == Setup
  
  
negative.code: which will build the HTML documentation into the folder _build/html_.
  
  The source code also contains a link:../Guardfile[Guardfile] for the https://github.com/guard/guard[Guard] library.
  You can execute:
  
  ----
  $ bundle exec guard
  ----
  
  and your HTML documentation will be automatically updated on each change to an Asciidoc source file.
