Appendix B. Creating a Multilingual Site
One of the advantages of the current version of Joomla is that it makes it really easy to create a multilingual website, without installing extensions. This is especially the case if you want to set up a multilingual site from scratch; while installing Joomla, you can follow a couple of extra steps to automatically install and enable the multilingual functionality. In this appendix, you'll find a complete walkthrough of the steps involved.
If you've already got a Joomla-powered site with content in one language and want to make it multilingual afterwards, a bit more effort is required. You need to add the required language packs and extensions yourself. You'll find more information on this procedure in the second part of this appendix.
