Want to add rspec to my rails 3 app, what do I need to do?

I updated my GEMFile with:

 group :development, :test do

    gem 'rspec'
    gem 'webrat'
    gem 'rspec-rails'
 end

And ran bundle install.

Now I already have a HomeController, so I manually created this:

/spec/controllers/home_controller_spec.rb

I don't have an about page so I started my test off with:

require 'spec_helper'

describe HomeController do

  describe "Get 'about'" do
    it "should be successful" do
      get 'about'
      response.should be_success
    end
  end


end

Now I did:

rspec spec/

Do I need to update some other files for rspec to work, don't understand this error message.

UPDATE

I changed the if to it, now I'm getting:

See the top line of the backtrace.

/Users/someuser/dev/rscs/example.com/spec/controllers/home_controller_spec.rb:6: syntax error, unexpected kDO, expecting kTHEN or ':' or '\n' or ';' (SyntaxError)

That error message points to a syntax error in your spec file—namely, on line 6, there is a do where it was not expected. That's where you should check first.

if "should be successful" do

I'm betting you meant that if to be an it ;) it is the RSpec method for defining a particular aspect of the class to test, and it, unlike the if operator, can take a block.
