I’m trying to update my rails from 2.3.8 to 3.0, where can I get the kit  
from ?

Thanks,  
Dani

If you want to upgrade from previous versions, I suggest you look into

I haven’t really played with Rails 3 that serious. I am still using  
2.3.8, and will only jump to rails 3 when it is production ready. But  
I have been playing with it from time to time and following quite a  
few books and tutorials.

Regards,

Fidel.
