 # LOCALISATION
 
 Available localisation for the default "client-menu" is only shown if no
 "client-menu" is present in menu.xml. Any menu definition in menu.xml is
 interpreted as a user-override.
 
+# YAML SUPPORT
+
+Like rc.yaml, labwc supports menu.yaml instead of menu.xml. See labwc-config(5)
+for its syntax. Note that following keys in singular form can be expressed as
+plural form in menu.yaml:
+
+	- *menus* (converted to *menu*)
+	- *items* (converted to *item*)
+
+See /usr/share/docs/labwc/menu.yaml for an example menu configuration in YAML.
