Pandoc understands an extended and slightly revised version of John
Gruber’s Markdown
syntax. This document explains the syntax, noting differences from
original Markdown. Except where noted, these differences can be
suppressed by using the markdown_strict format instead of
markdown. Extensions can be enabled or disabled to specify
the behavior more granularly. They are described in the following. See
also Extensions above, for
extensions that work also on other formats.
