Confused on handing over to client

Hello, I really hope someone can help!

I have created a website for a client who owns a restaurant.
It looks good and I have almost finished.
It contains a order delivery and reserve table page.

I wanted to know the steps on completing a website for a customer and how they make changes to information themselves. without having to use the editor.

Thankyou all!
