+# Batman-Rails
+
+Easily setup and use batman.js (0.6.0) with rails 3.1
+
+## Rails 3.1 setup
+This gem requires the use of rails 3.1, coffeescript and the new rails asset pipeline provided by sprockets.
+
+This gem vendors the latest version of batman.js for Rails 3.1 and greater. The files will be added to the asset pipeline and available for you to use. 
+    
+### Installation
+
+In your Gemfile, add this line:
+
+    gem "batman-rails"
+  
+Then run the following commands:
+
+    bundle install
+    rails g batman:install
+
+### Layout and namespacing
+
+Running `rails g batman:install` will create the following directory structure under `app/assets/javascripts/`:
+  
+    controllers/
+    models/
+    helpers/
+    
+It will also create a toplevel app_name.coffee file to setup namespacing and setup initial requires.
+    
+## Generators
+batman-rails provides 3 simple generators to help get you started using batman.js with rails 3.1. 
+The generators will only create client side code (javascript).
+
+### Model Generator
+
+    rails g batman:model
+    
+This generator creates a batman model and collection inside `app/assets/javascript/models` to be used to talk to the rails backend.
+
+### Controllers
+    
+    rails g batman:controller
+    
+This generator creates a batman controller for the given actions provided.
+
+### Scaffolding
+
+    rails g batman:scaffold
+    
+This generator creates a controller, helper and mode to create a simple crud single page app
+
+## Example Usage
+
+Created a new rails 3.1 application called `blog`.
+
+    rails new blog
+
+Edit your Gemfile and add
+
+    gem 'batman-rails'
+
+Install the gem and generate scaffolding.
+
+    bundle install
+    rails g batman:install
+    rails g scaffold Post title:string content:string
+    rake db:migrate
+    rails g batman:scaffold Post title:string content:string
+    
+You now have installed the batman-rails gem, setup a default directory structure for your frontend batman code. 
+Then you generated the usual rails server side crud scaffolding and finally generated batman.js code to provide a simple single page crud app.
+You have one last step:
