Please assume good intent with this comment. I had a bit of difficulty reading this because I was side-tracked by this sentence structure, which appears a few times throughout... "Here’s how my paper notes look like". I see this quite often and I'm having trouble figuring out what to search for to explain it and check if it's correct, and foreign to me, or if it's incorrect. I suspect it's incorrect and that it should either be, "Here's how my paper notes look" or "Here's what my paper notes look like". Can anyone enlighten me on why I see this structure a lot?
