There are some great guides on the web to get started :

Evan Miller Guide To Nginx Module Development [1] and advanced topics [2]
A bit old, but definitely not dated if you want to learn how it works
inside.

Nginx Guts [3] also has quite a few articles on the core of Nginx.

If you're interested in adding new features, you can find many Nginx [4] or
3rd-party modules [5],
they all add new extensions and capabilities to the core of Nginx.

As for the main() I think it parses the command line options, reads the
configuration and spawn the worker processes.
Then each worker process will start accepting and processing HTTP requests.

Hope that helps,

Matthieu.
