On this page you will find quickstart packages for the Joomla! 3 version including various German language versions for immediate download:
Germany (de-DE), Austria (de-AT), Switzerland (de-CH), Liechtenstein (de-LI), Luxembourg (de-LU)
Note: For many extensions there is only the German language package "de-DE". If another language variant is set as the standard language, the extension would be displayed in English.
Quickstart packages are ideal if you want to build a new website or quickly create a test version without having to collect and install the individual components, modules or plugins.
Note: The quickstart package must be installed in an empty directory!
A MySQL database is required!
Instructions for installing the J3 Quickstart packages are available here: Manual
