positive.code: If you want to download a zip archive, click the btn:[Download Zip] button on the right-hand side of the repository page on GitHub.
  Once the download finishes, extract the archive, open a console and change to that directory.
  
  TIP: Instead of working out of the {project-handle} directory, you can simply add the absolute path of the [path]_bin_ directory to your +PATH+ environment variable.
  
  We'll leverage the project configuration to install the necessary dependencies.
  
  
negative.code: 
  The command will generate the file [file]_example-optimized.pdf_ in the current directory.
  
  WARNING: The `optimize-pdf` script currently requires a Bash shell (Linux, OSX, etc).
  We plan to rewrite the script in Ruby so it works across platforms (see https://github.com/asciidoctor/asciidoctor-pdf/issues/1[issue #1])
  
  IMPORTANT: The `optimize-pdf` script relies on Ghostscript >= 9.10.
  Otherwise, it may actually make the PDF larger.
  Also, you should only consider using it if the file size of the original PDF is > 5MB.
  
  If a file is found with the extension `.pdfmarks` and the same rootname as the input file, it is used to add metadata to the generated PDF document.
  This file is necessary to preserve the document metadata since Ghostscript will otherwise drop it.
  That's why Asciidoctor PDF always creates this file in addition to the PDF.
