[support] Drupal sites in different languages

Hello,

I am relatively new to Drupal and I am trying to set up a site in two different languages. I would be more than happy to hear some recommendations how to best proceed on this.

Do I need to set up two nodes for every page, one in language 1 and one in language 2, and then link them? Or do I create the site in one language and copy everything on it and translate it to the second language?

I saw that there are some modules, even one that comes with Drupal, but they all sound like they "just" translate the user interface. I don't care so much about that, for me the most important thing are the content and maybe the menus.

Any insights are greatly appreciated! :) Thanks, Andre
