+The `hidden` parameter can be used to hide a post from the index page. When `hidden: true` is set, the post will not appear in the index but will still be accessible in other ways (e.g., the archive page or via a direct link).

+```yml

+title: Secret Post

+hidden: true

 ## Note
 
 If your theme define a non-archive `index` layout (e.g. About Me page), this plugin would follow that layout instead and not generate an archive. In that case, use [hexo-generator-archive](https://github.com/hexojs/hexo-generator-archive) to generate an archive according to the `archive` layout.
