This plugin lets you use <a href="https://github.com/erusev/parsedown" rel="nofollow ugc">Markdown</a> for individual posts on a case-by-case basis. <a href="https://github.com/thephpleague/html-to-markdown" rel="nofollow ugc">Markdown can be activated</a> using a toggle in the post editor submit box. When enabled, it replaces the WordPress post editor with <a href="https://make.wordpress.org/core/2017/10/22/code-editing-improvements-in-wordpress-4-9/" rel="nofollow ugc">CodeMirror</a> in Markdown mode.
Works on posts using the <a href="https://en-ca.wordpress.org/plugins/classic-editor/" rel="nofollow ugc">Classic Editor</a>. Gutenberg is currently not supported.
