+Language Cookie
+***************
+
+By default if someone visits a page at `http://www.mysite.fr/` django determines the language as follow:
+
+- language in url
+- language in session
+- language in cookie
+- language in from browser
+- LANGUAGE_CODE from settings
+
+No if i have a German browser and visit a page that is only English and French, it will choose the language that is
+in LANGUAGE_CODE. If this is English but i only speak French i have to switch the language. No if after sometime
+i visit the page again. The page will display in English again and I have to switch again. The same is for every
+link that points to `/` will switch to English again. To fix this behavior the cms ships with a middleware:
+
+    `cms.middleware.language.LanguageCookieMiddleware`
+
+add this to you middleware settings fix this.
