+## Tranlations
+
+We use [Babel](http://babel.pocoo.org/en/latest/) to translate Caravel. The
+key is to instrument the strings that need translation using
+`from flask.ext.babelpkg import lazy_gettext as _`. Once this is imported in
+a module, all you have to do is to `_("Wrap your strings")` using the
+underscore `_` "function".
+
+To enable changing language in your environment, you can simply add the
+`LANGUAGES` parameter to your `caravel_config.py`. Having more than one
+options here will add a language selection dropdown on the right side of the
+navigation bar.
+
+    LANGUAGES = {
+        'en': {'flag': 'us', 'name': 'English'},
+        'fr': {'flag': 'fr', 'name': 'French'},
+        'zh': {'flag': 'cn', 'name': 'Chinese'},
+    }
+
+As per the [Flask AppBuilder documentation] about translation, to create a
+new language dictionary, run the following command:
+
+    pybabel init -i ./babel/messages.pot -d caravel/translations -l es
+
+Then it's a matter of running the statement bellow to gather all stings that
+need translation
+
+    fabmanager babel-extract --target caravel/translations/
+
+You can then translate the strings gathered in files located under
+`caravel/translation`, where there's one per language. For the translations
+to take effect, they need to be compiled using this command:
+
+    fabmanager babel-compile --target caravel/translations/
