Ultimate Markdown – Markdown Editor, Importer, & Exporter Plugin

Ultimate Markdown is a plugin for WordPress that allows you to create WordPress posts with the popular Markdown syntax.

Specifically, after installing the plugin, you will be able to:

• Create posts with perfectly formatted blocks from existing Markdown files or Markdown documents created with the plugin.
