The Markdown export back-end, “md”, converts an Org file to Markdown format, as defined at https://daringfireball.net/projects/markdown/.
Since it is built on top of the HTML back-end (see HTML Export), it converts every Org construct not defined in Markdown syntax, such as tables, to HTML.
Export to a text file with Markdown syntax. For ‘myfile.org’, Org exports to ‘myfile.md’, overwritten without warning.
Export to a temporary buffer. Does not create a file.
Export as a text file with Markdown syntax, then open it.
org-md-headline-style, Markdown export can generate
headlines of both atx and setext types. atx limits headline
levels to two whereas setext limits headline levels to six. Beyond
these limits, the export back-end converts headlines to lists. To set
a limit to a level before the absolute limit (see Export Settings).
