The goal of the project is to create an interface to install language packs from a generated list of accredited language packs during Joomla installation and subsequently from the administrator interface.
The Joomla! community has always been very committed to improve the internationalization in all the areas of the project. As a result, there are translations available into more than 60 languages. In my opinion, supporting other languages than English is particularly important for the Joomla! CMS. We must take into account that Joomla! is used around the globe, mainly by people who are non-native English speakers. Being one of them, I have been always concerned about making Joomla accessible for everyone.
In the current version, users can install and use Joomla in their own language. Sadly, there are still some steps that need to be done in English: after installing Jommla on the server, users must navigate in English through the Joomla Administration until they find the installer that allows them to add their preferred language package. This represents a language barrier for some users. I believe we will make a big step forward avoiding this mentioned step. Brief, this is the main goal of this Google Summer of Code project: to allow users to install and manage Joomla! entirely in the language they prefer.
