+## 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".
