Truly amazed by your work here - mind explaining how recommendations work?

HI!

I wanted to use this opportunity to tell you that I'm amazed by the amount of effort put into this. It looks great!

I also wanted to ask you if you wouldn't mind explaining how the app builds the user recommendations. I read the code multiple times, but I'm still confused as it's a complex topic.

Thank you!
