   To build the examples, simply run the npm `examples` task from the root of the project:
   
  - $ npm run examples
  + $ npm run examples --prefix packages/core
   
  -This command produces 3 examples in the [path]_build/examples_ directory:

  -* `asciidoctor_example.html` and `userguide_test.html` demonstrate how a Ruby script can be compiled to JavaScript using the Opal Compiler and displayed within the browser as a normal HTML file.
  -Both Ruby scripts `asciidoctor_example.rb` and `userguide_test.rb` include:
  +* `userguide_test.html` demonstrate how a Ruby script can be compiled to JavaScript using the Opal Compiler and displayed within the browser as a normal HTML file.
  +The Ruby script `userguide_test.rb` includes:
   ** a string that contains an AsciiDoc source document
   ** a call to the Asciidoctor API to render the content of that string to HTML
   ** an event listener that inserts the generated HTML into the page
  -* `slide.html` demonstrates how to convert an AsciiDoc content to a Reveal.js presentation using the Asciidoctor Reveal.js backend templates
  +* `basic.html` demonstrates how to convert an inline AsciiDoc content and insert the result in the HTML page
  +* `asciidoctor_example.html` demonstrates how to convert a file using the include directive and insert the result in the HTML page
   
   In order to visualize the result, a local http server must be started within the root of this project otherwise you will have a cross origin issue which prevents to load some resources and render the HTML.
  -For this purpose, you can run the following command to start a HTTP server locally: `npm run server`

   Once the server is listening, you can point your browser at:
   
  
positive.code: 
  For instance to build against Asciidoctor (Ruby) v1.5.8 use:
  
   $ ASCIIDOCTOR_CORE_VERSION=v1.5.8 npm run build
  
  ==== Using "quick" mode
  
  By default the build will run the whole tests suite but if you want to quickly iterate on your code, we recommend to use the task `build:quick`:
  
   $ npm run build:quick
  
  This task will run only the tests against a Node.js environment.
  
  
negative.code: 
   $ git clone https://github.com/asciidoctor/asciidoctor.js.git
  
  Next, run npm's `install` command:
  
   $ npm i
   $ npm i --prefix packages/core
  
  You're now ready to build Asciidoctor.js.
  
  TIP: Opal.js, the Ruby runtime in JavaScript is available in `packages/core/node_modules/asciidoctor-opal-runtime/src/opal.js`
