The user interface is available in English, Spanish, French, German, Portuguese and Dutch.
Please note that some parts of the interface are only available in English for the time being. The remaining translations will be added soon.
You can select the desired language via the user profile:
Go to your user, on the right-hand side, press on the three dots > edit >

For now, if you select a language other than English, some text may still appear in English. Translation will be completed gradually. Thank you for your patience.
