To use a descending order (newest articles first), also add <code>$config['pages_order'] = 'desc';</code>. The former won't affect pages without a <code>Date</code> meta header, but the latter does. To use ascending order for your page navigation again, add Twigs <code>reverse</code> filter to the navigation loop (<code>{&#37; for page in pages|reverse &#37;}...{&#37; endfor &#37;}}</code>) in your themes <code>index.twig</code>.

+Additional to Twigs extensive list of filters, functions and tags, Pico also provides some useful additional filters to make theming easier. You can parse any Markdown string to HTML using the `markdown` filter. Arrays can be sorted by one of its keys or a arbitrary deep sub-key using the `sort_by` filter (e.g. `{% for page in pages|sort_by("meta:nav"|split(":")) %}...{% endfor %}` iterates through all pages, ordered by the `nav` meta header; please note the `"meta:nav"|split(":")` part of the example, which passes `['meta', 'nav']` to the filter describing a key path). You can return all values of a given key or key path of an array using the `map` filter (e.g. `{{ pages|map("title") }}` returns all page titles).
+
 You can use different templates for different content files by specifying the `Template` meta header. Simply add e.g. `Template: blog-post` to a content file and Pico will use the `blog-post.twig` file in your theme folder to render the page.
 
 You don't have to create your own theme if Pico's default theme isn't sufficient for you, you can use one of the great themes third-party developers and designers created in the past. As with plugins, you can find themes in [our Wiki][WikiThemes].
