+## How Django chooses which language to use
+REST framework will use the same preferences to select which language to display as Django does.  You can find more info in the [django docs on discovering language preferences][django-language-preference].  For reference, these are
+
+1. First, it looks for the language prefix in the requested URL
+2. Failing that, it looks for the `LANGUAGE_SESSION_KEY` key in the current user’s session.
+3. Failing that, it looks for a cookie
+4. Failing that, it looks at the `Accept-Language` HTTP header.
+5. Failing that, it uses the global `LANGUAGE_CODE` setting.

+
+**Note:** You'll need to include the `django.middleware.locale.LocaleMiddleware` to enable any of the per-request language preferences.
