translation generator

README.md

@@ -88,6 +88,8 @@ To add a new language, create a new file in that directory.
 The name of the file should be the two-letters [ISO-639-1 language code](http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
 The language has to be referenced in the `languages.properties` file to be picked up.
 
+When adding new terms translations, add them in en.properties then run `mvn -e groovy:execute -Pi18n``. It will parse the english file and add new entries in the other translation files.
