[How I can create a new nation in FM 2012?]

I'm trying to create a new nation (fictional) in this new FM 2012 with subsequent competitions.

But to be honest I find the way to go, especially to enable any of the extinct nations to use based on my new project.

If someone is kind enough to explain step by step or else guide me to some specific post where you can find detailed information would be helpful.
