\writestatus{loading}{ConTeXt Modules / MarkDown Renderer}

%D This module deals with markdown which is a document encoding that
%D some \CONTEXT\ like much. It reminds me of the kind of minimal coding
%D we used before we ran into \TEX\ and were using a somewhat simple
%D rendering (pagination, etc) of documents. As I'm no user myself, it
%D is up to others to provide documentation and examples.
