  # Using SVG format (Scalable Vector Graphics) is highly recommended to
  # load logos, icons, text, and simple images. You can compress .SVG files
  # further using GZIP to create .SVGZ files. However, most browsers don’t
  # know that they need to decompress them first if they’re not served
  # without an appropriate ‘content-encoding’ HTTP response header. Thus,
  # these images wouldn’t show up in the browser. Hence, this module.
