<h3>Usage</h3>
<ol>
<li>Open <code>wp-content/themes/<YOUR THEME NAME>/index.php</code></li>
<li>You may place it in archive.php, single.php, post.php or page.php also.</li>
<li>Find: <code><?php while (have_posts()) : the_post(); ?></code></li>
<li>Add Anywhere Below It (The Place You Want The Ratings To Show): <code><?php if(function_exists('the_ratings')) { the_ratings(); } ?></code></li>
</ol>
<ul>
<li>If you DO NOT want the ratings to appear in every post/page, DO NOT use the code above. Just type in <code>[ratings]</code> into the selected post/page content and it will embed ratings into that post/page only.</li>
<li>If you want to embed other post ratings use <code>[ratings id="1"]</code>, where 1 is the ID of the post/page ratings that you want to display.</li>
<li>If you want to embed other post ratings results, use <code>[ratings id="1" results="true"]</code>, where 1 is the ID of the post/page ratings results that you want to display.</li>
</ul>
