Adds buttons to the Text (HTML) edit which generate Markdown syntax. These buttons serve as a great introduction to 
users who are new to Markdown, as well as shortcuts for more experienced users. The buttons include:
<ul>
<li>Bold</li>
<li>Italic</li>
<li>Blockquote</li>
<li>Link</li>
<li>Code</li>
<li>Table</li>
<li>Headers</li>
<li>Help (links to external Github Markdown guide)</li>
</ul>
This plugin does not modify the Visual editor, as that editor is not ideal for writing Markdown in. It’s recommended you disable 
the Visual editor entirely to enforce using Markdown.
Note that this plugin does not render Markdown. You should use a plugin (such as Jetpack Markdown) to render markdown in your theme.

This plugin replaces the Gutenberg block editor (or the classic TinyMCE) on the edit screen with <a href="https://github.com/Ionaru/easy-markdown-editor" rel="nofollow ugc">EasyMDE</a>, a markdown editor based on CodeMirror, fine-tuned to work smoothly with the WordPress admin panels.
The content is saved with the markdown syntax in the database and is rendered on the frontend thanks to the <a href="https://parsedown.org" rel="nofollow ugc">Parsedown</a> PHP library after being sanitized via WordPress native filters.
That’s pretty all you should know. It’s under active development, keep in touch and feel free <a href="https://wordpress.org/support/plugin/markup-markdown/" rel="ugc">to drop a line on the forum</a>, <a href="https://wordpress.org/support/plugin/markup-markdown/reviews/" rel="ugc">to let a rating</a> or even support me by buying a coffee !

Markup Markdown


Just a fact: all the main AI GPTs generate Markdown by default. If you can't beat 'em, join 'em! I LOVE this plugin, as I can now create AI style websites on the WordPress platform. If you notice: all the main commercial AI sites have a similar "A.I. Style". Which is - dark or light mode, a chat box, and the most important thing: Markdown. Anyway, I'm using this plugin. Great stuff!



My one nitpick - The plugin generates configuration files in wp-content. This is bad news and there is no reason for it. On many sites wp-content is publicly exposed to the internet. Anyway, this data should be move to site options in the database.

Disable Wordpress's native Gutenberg or TinyMCE editor in favor of a Markdown editor.
