+      Yelp is the GNOME help viewer. It is the default Mallard viewer, but it
+      can also display DocBook, info, man, and HTML documentation.
+    </_p>
+    <_p>
+      It makes it easy to find the documentation you need, with interactive
+      search and bookmarks.
+    </_p>
+    <_p>
+      It also has an editor mode, which shows editorial comments and revision
+      statuses when editing Mallard documents.
