<p>This plugin allows you to compose content in Markdown on a per-item basis. The markdown version is stored separately (in the <code>post_content_filtered</code> column), so you can deactivate this plugin and your posts won’t spew out Markdown, because HTML is stored in the <code>post_content</code>, just like normal. This is also much faster than doing on-the-fly Markdown conversion on every page load. It’s only done once! When you re-edit the post, the markdown version is swapped into the editor for you to edit. If something external updates the post content, you’ll lose the Markdown version.</p>
<p>Note: this plugin assumes you’re using the Classic editor.</p>


Markdown on Save

Allows you to compose content in Markdown on a per-item basis. The markdown version is stored separately, so you can deactivate this plugin any time.

<p>Markdown for P2 will enable Markdown formatting within your status updates and comments.</p>
<p>If you use P2 for any stretch of time you might find yourself in a situation where you start typing out HTML. Since posting from P2 happens (or should) entirely from the front end of the theme, by default formatting options aren’t available. So if you want to format a list, let’s say, you might be tempted to start typing out <code>ul</code> and <code>li</code> tags. Or perhaps add formatting buttons that might clutter up the interface.</p>
<p>Markdown for P2 is another option, and will allow you to use the Markdown format when you post to P2. Learn more about Markdown <a href="http://daringfireball.net/projects/markdown/" rel="nofollow ugc">at John Gruber’s site</a>.</p>

<li><a href="http://daringfireball.net/projects/markdown/" rel="nofollow ugc">Markdown</a>, of course, is a John Gruber production.</li>
<li>This plugin is almost entirely the work of <a href="http://michelf.com/projects/php-markdown/" rel="nofollow ugc">Michel Fortin</a> (released under the GPL, his copyright is included in the file), but wasn’t bundled into a neat plugin on WordPress dot org, and not specifically for this purpose. The credit for that code goes to…</li>
<li>Markdown support added using Adam Backstrom’s code via this <a href="https://gist.github.com/1561020" rel="nofollow ugc">Github Gist</a>.</li>

</ul>
<h3>Note</h3>
<p><em>Technically</em> this plugin will work with any WordPress site — it simply checks the_content and comment_text for Markdown — but this plugin is really only tested with P2. If you’re interested in using Markdown on your non-P2 blog, I’d recommend <a href="https://wordpress.org/extend/plugins/markdown-on-save/" rel="ugc">Markdown on Save</a> which I think will provide a better user experience in that situation.</p>
