Go to the Contentinterface. Here you will find the Create content function. You will need to enter a title, subtitle and category. Here you also decide in which language you want to create the content. At present you can choose between English, Polish, Spanish and German. More languages will follow shortly. Then you create your content.
To assign or remove a language later on: Open the content in question. Under the title and subtitle, you can see in which language you have already created the content. Now edit, add or remove a language.
Important information: The multilingual feature is only enabled for users with a Pro or Enterprise subscription. You may require an upgrade. To change your subscription, go to the SUBSCRIPTION menu item.
