How do I change my interface language?

​goorm service supports Korean, English and Japanese interfaces and can be changed through the dropbox on the top right of the site.
When you change the goormIDE language setting, the interface language of the container changes as well. You can also change the language setting inside the container. You can change the language setting via the [goormIDE] > [Preferences] or Alt + P.
The language you change inside the container is only valid until the container closes.
