To display indented paragraphs you can use the quote environment which is started with !begin_quote and finished with !end_quote. You can use the quote environment inside another quote environment or inside other environments.
This environment is useful to emphasize passages. This effect is used in the following example:
!begin_quote This paragraph is used inside a quote environment and will be displayed indented. !end_quote
This paragraph is used inside a quote environment and will be displayed indented.
