  * The SSViewer class handles rendering of .ss templates.  In addition to a full template in
  * the views folder, a template in views/Content or views/Layout will be rendered into $Content and
  * $Layout, respectively.
+ * 
+ * <b>Caching</b>
  *
  * Compiled templates are cached.  If you put ?flush=1 on your URL, it will force the template to be recompiled.  This
  * is a hack; the system should really detect when a page needs re-fetching.
  * 
+ * <b>Manifest File and Structure</b>
+ * 
  * Works with the global $_TEMPLATE_MANIFEST which is compiled by {@link ManifestBuilder->getTemplateManifest()}.
  * This associative array lists all template filepaths by "identifier", meaning the name
  * of the template without its path or extension.
