This is a snippet-module. This means it installs as a module, but is not a page section, rather you call it with the php function
ShowFeed();
You can place this in your template file, or any code section.
It puts the standard RSS button that links to rss.php - this file generates an rss 2.0 compatible feed that you can add to your favorite reader.
It feeds the last 10 (public only) pages (can be modified in rss.php) to be updated on your site, newest to oldest and includes the site title with link to the page, the date/time the page was updated, and if you have given the page a custom description via the page settings, it displays that as well.
You can see it in action as part of my template at
