 ## Usage
 
-Add this to your `environment.rb`:
+Add this to your `Gemfile`:
 
-    config.gem 'gravtastic', :version => '>= 2.1.0'
+    gem 'gravtastic'
 
 Next, say that you want a Gravatar for your model:
 
     class User < ActiveRecord::Base
       is_gravtastic!

 Now all your Gravatars will come from a secure connection, be a GIF and be 120x120px. The email will also come from the `author_email` field, not the default `email` field. Don't worry, you arn't locked into these defaults (you can override them by passing options to `#gravatar_url` like before).
 
 _Note: You can use either `is_gravtastic!` or `is_gravtastic`, they both do the same thing._
