Erlega is multi-language ready and is set by default to English as the main language. To add/edit or remove a language navigate to the language settings inside your kirby dashboard. Click on Add a new language
and fill in the required fields. Make sure to enter the correct language code. A list of available language codes can be found on Wikipedia.
Once you've added multiple languages you'll now have a language select option on each page inside the panel. To change the text simply switch between the languages and edit the page content.
