<h2>How to Install</h2>
<p style="font-size:1.1em;">In most cases, to use this plugin you will not need to change anything, however if its not working you will either need to:</p>
<ol>
<li>Check your 'pages' widget in the WP admin panel under the Presentation>Widgets tab and click the little icon on the pages widget and ensure that <strong>sort by</strong> is set to <strong>'page order'</strong>. </li>
<li>If you want the pages listed else-where or do not use the widgets or want you would like to use the excludePagesFeature, then you need to edit your template as shown below:
<ol style="list-style-type:upper-roman;">
<li style="margin-bottom:0;">To use the code in your sidebar.php file you need to remove all widgets in your WP admin to active the sidebar code and then find the <strong>wp_list_pages()</strong> function and change it to the code below </li>
<li style="margin-bottom:0;">To insert the pages in your header; modify header.php insert the code anywhere inside the body tag. (You may want to add the depth=1 parameter on the 2nd line if you only want top level pages listed)</li>
</ol>
Then to enable the excludePagesFeature find the line $excludePagesFeature = false; near the top of pagemash.php and change the value to true.
</li>
</ol>
<p style="margin-bottom:0; font-weight:bold;">Code:</p>

<p>The plugin code is very simple and flexible, for more information look at the wp_list_pages() function on the <a href="http://codex.wordpress.org/Template_Tags/wp_list_pages" title="wp_list_pages Documentation">Wordpress Codex</a> and if you have any further questions or feedback, just <a href="http://joelstarnes.co.uk/contact/" title="email Joel Starnes">drop me an email</a>.</p>
