+### Links appearance
+
+When `po_translation_status_in_links` is enabled, the text of a link
+to a slave pages displays this page's translation status.
+
+When the `po_strictly_refresh_backlinks` setting is enabled, a page is
+refreshed every time a backlinked page is changed. This updates the
+translation status in links, and helps having a consistent translated
+wiki. Beware, this make every page depend on every page that links to
+it, which can slow everything down and bloat the dependency pagespecs.
