Wix Multilingual & Wix SEO (Get Found On Google)

I am puzzled as to how the Multilingual app works. I was told that I have to manually translate each area of text separately to the specified language I want. And by that, would you take the text into an online translation app and plug in the original text and then translate to the desired language and then place that new translated text into the Wix Mutilingual App? Sounds cumbersome, but is this the way to do it?
