        Embedding images on PDF documents is fairly easy. Prawn supports both
        JPG and PNG images.

        The examples show:
      TEXT

      list(
        'How to add an image to a page',
        'How place the image on a specific position',
        'How to configure the image dimensions by setting the width and '\
          'height or by scaling it'
      )
    end
  end
