[Markdown](http://daringfireball.net/projects/markdown/) is a minimal markup language that resembles plain text as used in email messages. It is the markup language used by this wiki by default. For documentation about the markdown syntax, see [[HelpOnFormatting]] and [Markdown: syntax](http://daringfireball.net/projects/markdown/syntax). A [markdown mode](http://jrblevin.freeshell.org/software/markdown-mode/) for emacs can help in editing. Note that [[WikiLink]]s and [[PreProcessorDirective]]s are not part of the markdown syntax, and are the only bit of markup that this wiki handles internally.
