Projects can be published into multiple languages. The purpose of this is to (automatically) guide viewers to the correct language of your publications, either through search engines or manually from the overview page. This will also display the correct language in the side menu of your publications. To be able to create a project in a certain language, you first need to set your languages in the language settings in the dashboard. Click here to see how to choose set and configure these languages.
To change the language of your project, open the project and go to the project settings from the page overview. Under the basic information tab, you will see a language. From here, you can choose a language for your project out of the languages you chose in the language settings of the dashboard.
