Any Olaf mains could gimme some tips in playing Olaf top?

Yeah I checked league champ wiki to know all the important builds & skill points, but even when I play Olaf as just a jungler, it felt like there's so many tips I've been missing out. I would really like to try Olaf top lane this time, as I felt a little motivated after watching Fnatics acing the win with an Olaf jungle.

Either Olaf tips for top lane & jungle is great, thanks.
