Ruby On Rails Getting Started question

[Eric Blow]

Hi All,
 I am going through the getting started guide here http://guides.rubyonrails.org/getting_started.html
And in section 5.7 it refers to a code snippet that I don't understand what to do with it.

post GET    /posts/:id(.:format)      posts#show

 

I don't understand if I am supposed to put this code somewhere or not. The guide doesn't tell me exactly. 
I also noticed the same sort of code is discussed in section 5.8 where it mentions 

posts GET    /posts(.:format)          posts#index

Any help would be great.

Thanks!

That's `rake routes` output, and translates roughly to:

`get "/posts/:id", :to => "posts#show", :as => :post` in config/routes.rb

I suggest working through the tutorial at railstutorial.org (which is free to use online).  For absolute beginners I think it is better than the rails guide.
