title: How to install paper_trail plugin on Rails 3
body: <p>I'm sure this is astonishingly straightforward, and I'm just inexperienced with Rails 3, but I can't figure out how to make it work.</p>
  
  <p>I'm trying to install the <a href="http://github.com/airblade/paper_trail" rel="nofollow noreferrer">paper_trail</a> plugin into my Rails 3 app; but the instructions seem designed for Rails 2. I'm running under Windows, and don't have git available.</p>
  
  <p>I've tried putting <code>gem 'paper_trail'</code> into my Gemfile and running <code>bundle install</code>, which picked up the gem correctly; but <code>rails generate paper_trail</code> (which I assume is the new form of <code>script/generate paper_trail</code> fails with <code>Could not find generator paper_trail.</code></p>
  
  <p>Can anyone give me some step-by-step instructions to get this working?</p>
