I'm happy that you found some of the information you were looking for. Perhaps I need to re-read our homepage too ;)
A language pack may already exist for your language, and if so, the process for using them is as simple as 3 steps:
1. Download the file from our
Language Packs page (just click on the relevant theme to see which languages are currently available)
2. Upload the file to your theme folder
3. Edit your
wp-config.php file (which just involves typing in 5 characters depending on your language code e.g. it_IT for Italian)
If a language pack does not exist, the theme can be easily translated using poedit software (
Detailed instructions here)
These languages packs are designed so that you can translate your theme into another language, but not so you can use multiple languages at the same time. You can find plugins which can do this job, however not all are compatible with our themes.
I hope this explains how it works in simple terms, but you can of course read the documentation contained in the link for more info also.
