How should i resign?

I'm planning to resign on Friday on my weekly 1:1 with my manager. I have a 1:1 with my director, which is on Wednesday should I say something to my director? I feel like is not his job, once I tell my manager he'll get the news shortly but feel weird to have the meeting with him like nothing and quit the next day. Also, is it fine to tell my manager about my resignation verbally and after that send the letter?
