      Prawn strips all whitespace from the beginning and the end of strings so
      there are two ways to indent paragraphs:

      One is to use non-breaking spaces which Prawn won't strip. One shortcut
      to using them is the <code>Prawn::Text::NBSP</code>.

      The other is to use the <code>:indent_paragraphs</code> option with the
      text methods. Just pass a number with the space to indent the first line
      in each paragraph.
    TEXT
  end

  example new_page: true do
    # Using non-breaking spaces
    text (' ' * 10) + ("This paragraph won't be indented. " * 10) +
      "\n#{Prawn::Text::NBSP * 10}" + ('This one will with NBSP. ' * 10)

    move_down 20
    text "#{'This paragraph will be indented. ' * 10}\n#{'This one will too. ' * 10}",
      indent_paragraphs: 60

    move_down 20
    text 'FROM RIGHT TO LEFT:'
    text "#{'This paragraph will be indented. ' * 10}\n#{'This one will too. ' * 10}",
      indent_paragraphs: 60,
      direction: :rtl
