1/ Child theme
We strongly recommend you to create a child theme and use it for customizing Chromium. This way you can update the theme and its plugins without fear of loosing implemented changes.
Theme use PO translation file which is the industry standard translation method. In the theme folder, you will find a folder called languages. You will find each languages files store in the folder.
- *.po – A lists of all text strings in theme. The text strings are in English and you can add the translation to each text string.
- *.mo – This is the compiled .po file and is used by WordPress to translate the theme
If your language isn’t included in the theme language files. You have to create a new .po file from the original Theme.po located in theme’s languages folder then save the new .po file with your language code for example de_DE.po
