+Reloading Translations
+----------------------
+
+The compiled translations will only be loaded initially. This means you have
+to restart the server whenever you compile translations and want to see
+those changes. To automatically reload translations you can tell the reloader
+to watch the compiled ``.mo`` files::
+
+    $ flask run --extra-files app/translations/en_GB/LC_MESSAGES/messages.mo
+    # or
+    $ export FLASK_RUN_EXTRA_FILES=app/translations/en_GB/LC_MESSAGES/messages.mo
+    $ flask run

+See `reloader`_ for more details.
