Anyone can provide me rails 3.0 manual

I'm very confused with it's command.The syntax very different from the older version.I 've already try google searching but I did not find.

                                                                Thanks

If you type rails on the command prompt, it will tell you the new syntax.

But you can always check the website guides.rubyonrails.org or this online book http://railstutorial.org

All the best,
