Help?

I am just starting to play this game can someone give me some advise for beginners?

Go through the first 10 level playing with bot learn how your skillshot and other champion work. you should be fine after you reach 20level +

Yeah, do some bot games and then play some aram games to play more champs you normaly wont pick.
If you have found a champ you can play with, then play some bot games and normal.
But I think you should search a friend who is playing lol too, its much more fun with friends^^
