The code should be self-explanatory for a developer, if not add documentation inside the code.

I like to document anything the client will have at some point to touch. Deployment and configuration must be documented.

There are two different things to consider: - Your client beeing able to deploy or use what you give them. - Your client beeing able to modify or add features to the existing code.

Always do the first one. I always discuss this kind of things before starting a project with the client. And everything discussed is mentioned inside the contract.
