        You have three options on how to use this plugin:
        <ol>
        <li>After entering your profile ID just put the shortcode <strong>[facebooksimplelike]</strong> where ever you want a simple like button for your fan page</li>
        <li>Use your theme's <a href="widgets.php">widgets interface</a> to add a like button</li>
        <li>Place as many like buttons to as many fan pages as you like via the this shortcode syntax:<br /><strong>[facebooksimplelike pageurl="http://www.facebook.com/mypage"]</strong></li>
        </ol>
