		<h2>How to Use</h2>
		<p>pageMash works with the wp_list_pages function. The easiest way to use it is to put the pages widget in your sidebar [WP admin page > Presentation > Widgets]. Click the configure button on the widget and ensure that 'sort by' is set to 'page order'. Hey presto, you're done.</p>
		<p>You can also use the function anywhere in your theme code. e.g. in your sidebar.php file (but the code in here will not run if you're using any widgets) or your header.php file (somewhere under the body tag, you may want to use the depth=1 parameter to only show top level pages). The code should look something like the following:</p>
		<p style="margin-bottom:0; font-weight:bold;">Code:</p>
		<code id="pageMash_code">
			<span class="white">&lt;?php</span> <span class="blue">wp_list_pages(</span><span class="orange">'title_li=&lt;h2&gt;Pages&lt;/h2&gt;&amp;depth=0'</span><span class="blue">);</span> <span class="white">?&gt;</span>
		</code>
		<p>You can also hard-code pages to exclude and these will be merged with the pages you set to exclude in your pageMash admin.</p>
		<p>The code here is very simple and flexible, for more information look up <a href="http://codex.wordpress.org/Template_Tags/wp_list_pages" title="wp_list_pages Documentation">wp_list_pages() in the Wordpress Codex</a> as it is very well documented and if you have any further questions or feedback I like getting messages, so <a href="http://joelstarnes.co.uk/contact/" title="email Joel Starnes">drop me an email</a>.</p>
