This is a simple plugin to help you write posts or pages in plain-text Markdown syntax. And even allowing plaint-text Markdown for comments as well. It will also switch-off the Visual Editor, as you don’t need distractions. This plugin sits on top of a giant’s shoulder, namely Jetpack.
This plugin is also installable via composer, see: https://github.com/7php/MarkItDownWordpress
<h3>Roadmap</h3>
<ul>
<li>By default, toggle the checkbox to true for Settings > Writing > ‘Use Markdown for posts and pages’</li>
<li>By default, toggle the checkbox to true for Settings > Discussion > ‘Use Markdown for comments’</li>
<li>In plain-tex editor mode, remove the short-formatting buttons, e.g [b, i, link, b-quote, del].. etc. Make the editor, distraction free.</li>
<li>Make an effort to provide Markdown buttons for the equivalent of [b, i, link, b-quote, del], just like bbcodes.</li>
</ul>

Mark It Down WordPress!

I just replaced JP Markdown (which is abandoned by now) with this plugin. The switch was easy and painless: 


Install this plugin and activate it
Deactivate JP Markdown
Set the flags under "Settings => Writing" and "Settings => Comments"
Done!


The posts written in Markdown are still written in markdown and still rendered as HTML as before, so a smooth transition from my POV.

Thanks!

WP-MediaWiki adds a subset of MediaWiki markups to WordPress. 
Currently, the following MediaWiki markups are supported.
<ul>
<li>Bold</li>
<li>Italic</li>
<li>Heading</li>
<li>Lists: Besides the list markups come from MediaWiki, I also added a continuation markup such that users can put preformatted text in a list item.</li>
<li>Tables</li>
<li>External links</li>
<li>WikiLinks: the wikilink will link to Wikipedia by default, you can change the wiki site in the admin option page.</li>
<li>Table of content</li>
<li>Horizontal line</li>
<li>Preformatted text</li>
</ul>
