1. Copy the 'Fonts' folder and CSS file to your website's CSS directory.
2. Add the CSS link in your website's `<head>` section: <head> ... <link rel="stylesheet" type="text/css" href="yourdomain.com/css_root/mk_sports_icons.css"> ... </head>
3. Use the corresponding class name on elements where you want to display an icon, for example: `<i class="flaticon-trophy"></i>` or `<span class="flaticon-stadium"></span>`.
