Similar to layouts, on creating a Firn site, you will find a folder: _firn/pages. This folder enables users to create custom pages that are converted from the template language (hiccup) into HTML. This is useful if you want to create a page that does not render any org-mode content.

Creating a new Firn site comes with a custom page: tags.clj. This file exists to provide an example of a custom page, as well as to give user's an out-of-the-box solution for displaying org-tags with Firn. When Firn processes your org-mode files, it collects all heading tags, and stores them in a Clojure vector (simply, a list). A user may access this list of tags directly, as they are made available to layouts and pages, or the list of tags can be rendered using a pre-set render function.

You can of course delete this file if you do not want to render tags.

"Pages" are not based around interpreting and constructing content from org-mode files. So, use of the (render) function is limited to performing renderings of site-wide content, such as the site-map (whereas rendering say, breadcrumbs, or an org-mode heading will not work.)
