How do I use Markdown syntax?

Please refer to this resource: PHP Markdown Extra.

How do I disable Markdown processing?

In most cases this should be unnecessary, since Markdown ignores existing HTML. But if Markdown for some reason disturbs your HTML when making an edit to a non-Markdown post, either check the "Disable Markdown formatting" checkbox, or put a <!--no-markdown--> HTML comment in your post somewhere (useful when using a mobile or 3rd party blogging app).

How do I convert an existing post to Markdown?

There is an experimental checkbox in the post editor to convert your old HTML post to Markdown using Markdownify. Check it at your own risk. Make sure you have revisions on or backups. If you're relying on specifically crafted HTML, it might get destroyed. But it might be cool.

What if I don't want to see that Markdown meta box at all?

I see you love Markdown greatly. You have chosen wisely. Add the following constant to your wp-config.php file:

define( 'SD_HIDE_MARKDOWN_BOX', true );

Note that you can still disable Markdown formatting with a <!--no-markdown--> HTML comment. HTML to Markdown conversion will be impossible.

What happens if I decide I don't want this plugin anymore?

Just deactivate it. The Markdown version is stored separately, so without the plugin, you'll just revert to editing the HTML version.
