How to install a git plugin on Rails 3

I'm completely new to Rails and just installed Rails 3 on Ubuntu 10.04. I was wondering if 开发者_开发问答someone could please explain how to install a plugin from a Git repository.

More specifically, I'm trying to install the restful-authentication plugin from the git repository: git://github.com/technoweenie/restful-authentication.git

Any advice would be greatly appreciated.

oops. sorry everyone. just found the answer:

rails plugin install git://github.com/technoweenie/restful-authentication.git
