+Decide which pages are translatable
+-----------------------------------
+
+The `po_translatable_pages` setting configures what pages are
+translatable. It is a [[ikiwiki/PageSpec]], so you have lots of
+control over what kind of pages are translatable.
+
+The `*.LL.po` translations files are anyway not considered as being
+translatable, so you don't need to worry about excluding them manually
+from this [[ikiwiki/PageSpec]].
+
+Internal links
+--------------
+
+One can use the `po_link_to_` option in `ikiwiki.setup` to choose how
+internal links should be generated, depending on web server features
+and site-specific preferences.
+
+### Default linking behavior
+
+If `po_link_to` is unset, or set to `default`, ikiwiki's default
+linking behavior is preserved: `[[page]]` links to the master
+language's page.
+
+### Link to negotiated language
+
+If `po_link_to` is set to `negotiated`, `[[page]]` links to the
+negotiated preferred language, *i.e.* `foo/page/`.
+
+(In)compatibility notes:
+
+- `po_link_to => negotiated` provides no useful behavior if `usedirs`
+  is disabled; this option combination is neither implemented nor
+  allowed
+- `po_link_to => negotiated` provides no useful behavior if the web
+  server does not support Content Negotiation
+
+### Link to current language
+
+If `po_link_to` is set to `current` and the destination page is either
+a translatable page or a translation, `[[page]]` links to the current
+page's language, *i.e.*:
+
+- `foo/page/index.LL.html` if `usedirs` is enabled
+- `foo/page.LL.html` if `usedirs` is disabled
