Insert a markdown TOC(Table Of Content) before posts be rendered.
Unlike the native toc helper, this plugin will inject a TOC only when a placeholder(<!-- toc -->) found in the raw markdown files. And the TOC will be injected after the placeholder.
All you need to do is placing a placeholder(<!-- toc -->) in your post when and where needed.
Note: this plugin will not mangle your posts(markdown files), so you can use it bold.
