How to edit: Edit Markdown by opening up article-example.html in a text
editor. Note that after build, this source file is replaced by pure HTML.
GUI editing: If you use a graphical Markdown editor, be sure to configure the starting "meta" format as the entire first line of this file (i.e. including the "script" tags AND the "---").
Limitations: The Modulo framework's built-in Markdown parser is geared toward quick docs. If you need more features (e.g. lists), it's recommended to swap in a new library.
