1. Copy the 'Fonts' folder and CSS file into your website's CSS directory.
2. Link the CSS file in the `<head>` section of your website. This ensures all icon styles are loaded correctly for display. <head> ... <link rel="stylesheet" type="text/css" href="your_website_domain/css_root/flaticon.css"> ... </head>
3. Apply the icon class to inline elements within your HTML. This is how you'll display specific icons on your pages. Usage example: <i class="flaticon-airplane49"></i> or <span class="flaticon-airplane49"></span>
