Since the first jDownloads version for Joomla 1.7, our translators have used the service from www.transifex.com .
In common with Joomla! itself, this is still the way translations are carried out. However we have now made it very simple to obtain language packages for the jDownloads project.
It is now very easy to find, download and then install language packages. If you should be unsure of how to download and then install a language package then the article Installing a language package will be helpful. All jDownloads releases comes with English and German language files preloaded.
It is now also possible for interested jDownloads users, to quickly add a missing language and start a new translation, and to help complete existing translations. You will need a Transifex account.
If you would like to help with the translations then the following this article may be of use:
The translations for the actual jDownloads series can be found on Transifex here. If you have any questions, please use the support forum. Many thanks.
