Rails 3 and Twitter bootstrap's sidebar (affix) - how?

Question

I have simple RoR 3.2 application with Twitter bootstrap 2.1.0 (i implemented it via twitter-bootstrap-rails gem). I want to integrate sidebar with few links (as you can see on twitter bootstrap page on the left side) but i can't get how to implement this (yes, i'm noob). Does anyone have solution how to do that in Rails?

My application layout:

!!!
%html
  %head
    %title MyApp
    = stylesheet_link_tag    "application", :media => "all"
    = javascript_include_tag "application"
    = csrf_meta_tags
    %meta{ :name => "viewport", :content => "width=device-width, initial-scale=1.0"  }
  %body
    %div{ :class => "wrapper" }
      = render 'layouts/navbar_template'

      %div{ :class => "container-fluid" }
        - flash.each do |key, msg|
          %div{ :class => "alert alert-#{key}" }
            %button{ :type => "button", :class => "close", "data-dismiss" =>"alert" }×
            = msg
        %div{ :class => "row-fluid" }
          %div{:class => "span10"}
            =yield
          %div{:class => "span2"}
            -# I would like to have sidebar here
