Font Awesome

GeneratePress no longer includes Font Awesome directly in the theme. Instead, you should use a plugin like this to add it to your site: Better Font Awesome

Font Awesome 5

The above plugin doesn’t include Font Awesome 5 yet. If you’d like to use it, you can use a function like this to include the library via their CDN.

add_action( 'wp_enqueue_scripts', 'tu_load_font_awesome' );
/**
 * Enqueue Font Awesome.
 */
function tu_load_font_awesome() {
    wp_enqueue_style( 'font-awesome', '//use.fontawesome.com/releases/v5.1.0/css/all.css', array(), '5.1.0' );
}

Old Theme Version

If you’re still using the Font Awesome 4 version that was included in the theme, you can remove it super easily by going to Customize > General and checking the Load essential icons only option.

Once this option is checked and saved, it will disappear the next time you load the Customizer.
