Looking for guidance/friends!

Hello, I just started playing league and I had a friend who taught me a little and bought me Olaf but he doesn't play anymore. I was wondering if anyone could help and give me more tips about the game. I wanna do this because I play by myself ( which is boring af ) and wanna make more friends that play this game. I feel I should mention I win most of my games with Olaf. Anyways my name is Extinct Parasite so hmu if you wanna help and teach me! aka I'm lvl 10 rn
