You can either translate content manually, or use the automatic translation feature.
Navigate to the text you want to translate. Click on the button of the desired target language below the text field, in this example DE (German).
Enter the translation and click on Save.
You can also "translate" images, i.e. store a separate image for each language:
Simply click on the translation symbol next to the picture, select the language for which the picture should be stored and the corresponding file, and click on Save.
Texts can be automatically translated into the selected target language by LOLYO. For detailed information see: How does the automatic translation work?
