+## Usage
+
 The site [http://yacd.haishan.me](http://yacd.haishan.me) is served with HTTP not HTTPS is because many browsers block requests to HTTP resources from a HTTPS website. If you think it's not safe, you could just download the [zip of the gh-pages](https://github.com/haishanh/yacd/archive/gh-pages.zip), unzip and serve those static files with a web server(like Nginx).
