 * [Discount](http://www.pell.portland.or.us/~orc/Code/discount/),
   via the [[!cpan Text::Markdown::Discount]] perl module.

+  This implementation is considered to be the default and is strongly
+  recommended, but it is not mandatory because it requires an external
+  C library.

 * The [[!cpan Text::Markdown]] perl module.
 * The [original version of markdown](http://daringfireball.net/projects/markdown/).
 
 [[!cpan Text::MultiMarkdown]] can be used in order to use tables, footnotes,

+## Advanced options
+
+* `nodiscount`: If set to 1, Text::Markdown::Discount will not be used
+  even if it is available. The default is to use Discount if available,
+  and this is recommended.
+* `multimarkdown`: If set to 1, Text::MultiMarkdown will be used in
+  preference to Text::Markdown::Discount. The default is to not use
+  MultiMarkdown, and this is recommended.
+* `mdwn_footnotes`: If set to 1, implementations that support it will
+  recognise the footnote syntax originating in PHP Markdown Extra, with
+  `Footnote reference[^1]` and `[^1]: Footnote definition`. The default
+  is 1.
+* `mdwn_alpha_lists`: If set to 1, Text::Markdown::Discount will
+  accept letters as well as numbers in ordered list markers. The
+  default is 0, to avoid unintended parsing of lines that happen
+  to begin with a letter and a dot, such as "C. S. Lewis was an
+  author" or "M. Descartes was a philosopher".
