+
+  <p>If your application handles files which could be printed or could be
+  represented well as a document, adding a thumbnailer makes the files show up
+  in <app>Files</app> with images that correspond to the document.</p>
+
+  <p>The gnome-desktop library defines the interface and associated files that
+  a thumbnailer must implement. The component responsible for calling the
+  thumbnailer is <link 
href="https://developer.gnome.org/gnome-desktop3/stable/GnomeDesktopThumbnailFactory.html";>GnomeDesktopThumbnailFactory</link>.</p>
+
+  <p>A common helper for thumbnailers, which handles the command-line parsing
+  and output file generation, is <link href="">gnome-thumbnailer-skeleton</link>.</p>
