+### How can I view Friendica in a certain language?
+
+You can do this by adding the `lang` parameter to the url in your url bar. The data in the parameter is a [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) code. eg. https://social.example.com/profile/example translated in German becomes https://social.example.com/profile/example?lang=de. If the question mark is already in the url you need to do it using a ampersand. eg. https://social.example.com/profile/example?tab=profile becomes https://social.example.com/profile/example&lang=de.
+
+When a certain language is forced, the language remains until session is closed.
