Duties of a Corporation ?

Creating a C-Corp is easy and one thing to do.

But once created, running the Corporation is another thing !
That being said, here is my question:

- What are the duties of a C-Corp ?

In terms of
- book keeping
- taxes
- license
- meetings
- etc.

I was not able to find any clear documentation about that chapter.
Any little help is highly appreciated.

Thank you so much !
