[solved] Contao 3.0 and multi language sites

Hello to everybody,
I already wrote a post but apparently lost it. I hope this does not appear twice ;-)

I was wondering, how do you implement multi-language websites with Contao 3.0? I read that i18nl10n is a loved extension used for this purpose, but sadly it's not compatible with C3.0

What are the best alternatives?

Thank you
cheers
Marco

the changelanguage extension is compatible with Contao 3

Thank you very much!
