 Let's build a simple Sinatra app using Sprockets and Sprockets::Helpers (See my fork of [sinatra-asset-pipeline](https://github.com/petebrowne/sinatra-asset-pipeline) for complete setup):
 
 ``` ruby
-require "sinatra/base"
-require "sprockets"
-require "sprockets-helpers"
+require 'sinatra/base'
+require 'sprockets'
+require 'sprockets-helpers'
 
 class App < Sinatra::Base
   set :sprockets, Sprockets::Environment.new(root)
-  set :assets_prefix, "/assets"
+  set :assets_prefix, '/assets'
   set :digest_assets, false
   
   configure do
     # Setup Sprockets
-    sprockets.append_path File.join(root, "assets", "stylesheets")
-    sprockets.append_path File.join(root, "assets", "javascripts")
-    sprockets.append_path File.join(root, "assets", "images")

+    sprockets.append_path File.join(root, 'assets', 'javascripts')
+    sprockets.append_path File.join(root, 'assets', 'images')
     
     # Configure Sprockets::Helpers (if necessary)

       config.environment = sprockets
       config.prefix      = assets_prefix

 Simply requiring sprockets-helpers will add the asset path helpers to the Sprocket context, making them available within any asset. For example, a file `assets/javascripts/paths.js.erb`:
 
 ``` js+erb
-var Paths = { railsImage: "<%= image_path "rails.png" %>" };
+var Paths = { railsImage: "<%= image_path 'rails.png' %>" };
 ```
 
 Would be transformed into:
 
 ``` javascript
-var Paths = { railsImage: "/assets/rails.png" };
+var Paths = { railsImage: '/assets/rails.png' };
 ```

 If the source is not an asset in the Sprockets environment, Sprockets::Helpers will fallback to looking for the file in the application's public directory. It will also append the cache busting timestamp of the file. For example:
 
 Given an image, `public/images/logo.jpg`:
 
 ``` html+erb
-<img src="<%= image_path "logo.jpg" %>">
+<img src="<%= image_path 'logo.jpg' %>">
 ```
 
 Would become:
 
 ``` html
-<img src="/images/logo.jpg?1320093919">
+<img src='/images/logo.jpg?1320093919'>
+```

+
+Manifest Usage
+--------------
+
+**New in 0.4**: Sprockets::Helpers will use the latest fingerprinted filename directly from a `manifest.json` file:
+
+
+``` ruby
+# ...
+Sprockets::Helpers.configure do |config|
+  config.environment = sprockets
+  config.manifest    = Sprockets::Manifest.new(sprockets, 'path/to/manifset.json')
+  config.prefix      = assets_prefix
+  config.public_path = public_folder
+end
+# ...
 ```
