eFront offers two types of language files: machine translated and human translated. Native, human translated language files are of better quality. We use a sophisticated system to ensure that future versions of eFront will keep all languages updated with newer tags while at the same time we will preserve human translations that are integrated to the system. We encourage native speakers of any of the following languages to help us with the translations.
How to use the language files: Just download the appropriate language pack and use the languages option on your eFront installation to upload it to your system.
