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.

npm install hexo-toc --save

All the options of markdown-toc, slugify function, and heading anchor options can be specified as follow in your _config.yml:

    position: after
