Ways to install streamlined

The versoin of rails I used is 2.0.2. I want rails work with
streamlined.
At first, I should install streamlined.
I try:

ruby script/plugin install git://github.com/relevance/streamlined

It says: Plugin not found: [“git://github.com/relevance/streamlined”]
And it appears an empty folder “streamlined” in vender\plugin

If you’re just starting a new Rails app, do not start with an old
version. You’ll end up tripping over bugs that have already been
fixed, and wasting a lot of time. Also, you’ll be missing features
that you need - for instance, installing plugins via Git, which was
added in (I think) the 2.2-era.
