Add the FlatPress CMS as a user

[Fraenkiman]

FlatPress is a flat file CMS that is almost 20 years old and is still being maintained and further developed today. I have created a plugin that makes it possible to use the parsedown parser under FlatPress.

The plugin can be downloaded from our wiki.

You mean adding a reference to FlatPress in the README's Who uses it section ?
