Once you set up multiple languages in a space, you can read pages in your preferred language.
To switch to another language, click the language picker and select a language.
The current page, and any other pages you view, display in the selected language.
A dialog displays if you view a page that hasn't been translated into the selected language. You can click a link on the dialog to display content on the page in the default language for the space.
