This theme is compatible with WPML – powerful plugin, that makes it easy to run a multilingual website with a single WordPress install. Choose languages for your site and start translating content.
The default install comes with over 40 languages. You can also add your own language variants (like Canadian French or Mexican Spanish) using WPML’s languages editor.
You can arrange different language contents in the same domain (in language directories), in sub-domains or in completely different domains.
Please visit WPML.org for more details.
