  - $ git clone --recurse-submodules git://github.com/nerk/asciidoctor-bs-themes
  + $ git clone --recurse-submodules https://github.com/nerk/asciidoctor-bs-themes
    
   NOTE: If you don't want to use GIT, you may also download the code as a +.zip+ file and unpack it 
   to a local directory.
  
positive.code: Next, switch to the 'asciidoctor-bs-themes' directory and generate the CSS files:
  
   $ cd asciidoctor-bs-themes
   $ buildcss
  
  This creates the following CSS files in directory +css+:
  
  
negative.code: You may test your created themes by generating some example documents from directory +test+:
  
   $ cd test
   $ ./gendoc
   
  This compiles the original AsciiDoc User Guide by Stuart Rackham and a file named 'test.adoc'
  for each of the generated styles and puts the HTML output into directory 'output'.
