Nowadays, you can define in Settings -> Guidebook settings in which languages the digital security guidance for personnel is maintained.
The template guidelines from Cyberday library are always automatically translated into all selected languages. Soon you will be able to take care of multilingualism in your own custom guidelines and in library guidelines you've edited.
You will see the content in the editing views of the guidelines separately in all the languages that you have selected to be available for the Guidebook.
