+Config mode texts
+-----------------
+
+The community-defined texts in the config mode are configured in PO files in the ``i18n`` subdirectory
+of the site configuration. The message IDs currently defined are:
+
+gluon-config-mode:welcome
+    Welcome text on the top of the config wizard page.
+
+gluon-config-mode:pubkey
+    Information about the public VPN key on the reboot page.
+
+gluon-config-mode:reboot
+    General information about the reboot page.
+
+There is a POT file in the site example directory which can be used to create templates
+for the language files. The command ``msginit -l en -i ../../docs/site-example/i18n/gluon-site.pot``
+can be used from the ``i18n`` directory to create an initial PO file called ``en.po`` if the ``gettext``
+utilities are installed.
