How to tell my crush I like him as more than friends?

I’ve been friends with this guy for about a year now but a few months ago I started developing feelings for him. He’s been really helpful and caring but I know he’s not ready for a relationship. He has told me before that he’s not looking because he wants to work on himself. That’s why I’m not even sure if I should tell him. If I did, how would a guy like a girl (friend) to tell him?
