Copy the 'Fonts' folder and the CSS file into your website's CSS directory.
Link the CSS file within the `<head>` section of your website's source code to ensure correct icon styling. <head> ... <link rel="stylesheet" type="text/css" href="your_website_domain/css_root/flaticon.css"> ... </head>
Apply the corresponding icon class to any 'display: inline' element to showcase stunning visuals. For instance: `<i class="flaticon-airplane49"></i>` or `<span class="flaticon-airplane49"></span>`.
