<p>A lot of different languages are available for the Back-end, but by default this language may not be installed. If you want a translated Back-end, get your language pack and install it using the Extension Installer. After this, go to the Extensions Menu, select Language Manager and make your language the default one. Your Back-end will be translated immediately.</p><p>Users who have access rights to the Back-end may choose the language they prefer in their Personal Details parameters. This is of also true for the Front-end language.</p><p> A good place to find where to download your languages and localised versions of Joomla! is <a href="http://extensions.joomla.org/index.php?option=com_mtree&task=listcats&cat_id=1837&Itemid=35" target="_blank" title="Translations for Joomla!">Translations for Joomla!</a> on JED.</p>
