As of this writing:

The Getting Started guide ([http://guides.rails.info/](http://guides.rails.info/)  
getting\_started.html) was recently re-written to reflect recent  
features in Rails 3.0. But the instructions it gives for downloading  
rails in section 3.1 (“gem install rails”) fetches rails 2.3.8, which  
won’t work for the given code. Not helpful to a newcomer.

So (is Mikel L. listening?) any one of these would be useful:

- The Guide should explain how to download Rails 3.0 (iff it is  
stable)
- The Guide should offer a pointer to Rails 2.3.8 compatible examples
- The Guide should be rolled back to Rails 2.3.8 until Rails 3.0 is  
the main version

(As a newcomer myself, let me know if there’s a more constructive  
place to direct this note. Thanks!)

On the front page of guides.rails.info it says ’

" There are two different versions of the Guides site, and you should  
be sure to use the one that applies to your situation:

Current Release version – based on Rails 2.3  
Edge version – based on the current Rails master branch"

with links to both.

for getting a Rails3 running enviroment.

This is true, but the UI design leaves a bit to be desired.

When you click on either link the page doesn’t change to show you  
which version you’ve selected.

Actually I lied a little bit. The only difference is that if you  
click the Current Release Version link the title just above says

Ruby on Rails guides

and when you click on Edge Version it changes to:

Ruby on Rails Guides

Which I guess makes it perfectly clear
