How can a user change the language?

You can switch to your preferred language by pressing the gearwheel on the right corner and entering the User settings.

Click on the language icon to see the drop-down of available languages. Select the language that you would like to use and press Save. The user interface will immediately switch to the language you have selected. You can click the arrow to return or the logo in the upper left corner to go to the dashboard.

If your preferred language is missing or unavailable, contact your IT administrator to ask him to activate it.
