  |===
  
  If you want to build a custom theme or customize an existing one you should
  look at `reveal.js's` documentation and use `revealjs_theme` attribute:
  https://github.com/hakimel/reveal.js/blob/master/css/theme/README.md
  
  === Examples
  
  
negative.code: == reveal.js Backend
  
  The https://github.com/asciidoctor/asciidoctor-backends/tree/master/slim/revealjs[reveal.js backend] is a collection of slim templates which transform an AsciiDoc document to HTML5 slides animated by http://lab.hakim.se/reveal-js/[reveal.js].
  
  === Installation
  
  First, you should download (or git clone) the https://github.com/asciidoctor/asciidoctor-backends[asciidoctor-backends] repository to a convenient location.
  
    git clone git://github.com/asciidoctor/asciidoctor-backends.git
  
  Then from your working directory (that is where your AsciiDoc document resides) you must create a +reveal.js+ directory and copy there the +reveal.js+ file with its directories (plugin, css, ...).
  You could also just clone the https://github.com/hakimel/reveal.js[reveal.js] repository.
  
    git clone git://github.com/hakimel/reveal.js.git
  
  === Settings
  
  There are some attributes that can be set at the top of the document which they are specific of +revealjs+ backend.
