			<p>Extract the zip's contents, look for the extracted plugin folder, and after you have all the new files upload them using FTP to the <strong>/wp-content/plugins/<?php echo $plugin_folder; ?></strong> folder overwriting the old ones (this is why it's important to backup any changes you've made to the plugin files).</p>
