+    @page apiroot API Root
+
+    The URLs for methods referred to in this API documentation are
+    relative to the StatusNet API root. The API root is determined by the
+    site's @b server and @b path variables, which are generally specified
+    in config.php. For example:
+
+    @code
+    $config['site']['server'] = 'example.org';
+    $config['site']['path'] = 'statusnet'
+    @endcode
+
+    The pattern for a site's API root is: @c protocol://server/path/api E.g:
+
+    @c http://example.org/statusnet/api
+
+    The @b path can be empty.  In that case the API root would simply be:
+
+    @c http://example.org/api
