iPhone not synching to new computer

I was doing some updates and my computer crashed. It is where I had iTunes syched with my iPhone.

I downloaded iTunes on my new computer and no synching option is coming up like it did on my other computer. It doesn't even show my iPhone name on the left side like the old one did.


What should I do differently? All I want to do is transfer some music to my iPhone that I transferred by my CD's into iTunes.
