In the WordPress world, they refer to translating WordPress as “locxalization” and so this theme comes “localization-ready”.
This is the complete guide to get you started:
Specifically to the theme, there is a file called akita.po located in the “lang” folder of the theme. You download that file and translate the contents line by line. This process will be easier to manage if you use a program like poEdit, for example. That way you’ll be able to translate the file with a user-friendly interface and not a text editor. Then you save the file with your language code in the file name (ex: fr_FR.po for French, en_BR.po for British, etc). When you do this, poEdit will also create a second file for you with the same name ending in “.mo”. Then you need to upload these two new files back to “lang” folder of the theme on your live site.
In order for the above process to work, you need to actually have your WordPress site set to be in your language. You do that by changing the language code in your wp-config.php file (which is found in the root directory or your WordPress installation). Here’s a guide on that process:
I’m also curious if there is possibility to create multilanguage site ?
You’ll want to look into using a plugin like WPML, which will actually give you an interface to accomplish all the stuff described above.
