1. Place the 'fonts' folder and the CSS file into your website's CSS directory.
2. Link the CSS file in the `<head>` section of your site: <head> ... <link rel="stylesheet" type="text/css" href="yourdomain.com/css_root/flaticon.css"> ... </head>
3. Use the icon class directly where you want to display it, like: `<i class="flaticon-gamepad"></i>` or `<span class="flaticon-gamepad"></span>`.
