+# Wallet
+
+Wallet, a simple ruby DSL for centralizing action cache configuration inside your Rails app.
+
+## Installation
+
+Wallet is a gem, available from http://rubygems.org. 
+
+Add the following to your Rails 3 app's Gemfile:
+
+    gem 'wallet', '~> 1.0'
+
+## Usage
+
+Let's imagine your app has a controller `HomeController`, and you want to action cache all of the
+actions inside of it. First, create a `config/wallet.rb` inside your rails root, then open your `Wallet` and add some `cash`:
+
+    Wallet.open do
+      cash :home
+    end
+
+Next, open your `ApplicationController`, and add the following into it: 
+
+    class ApplicationController < ActionController::Base
+      include Wallet::Cash
+      cash!
+    end
+
+The `cash!` method will setup action caching for your controllers (if they have any cache configuration in Wallet). 
+
+With this code in place, Rails will action cache every action inside your home controller for the default TTL (time-to-live) duration: 10 minutes. You can change the default ttl by passing a duration to the `default_ttl` method:
+
+    Wallet.default_ttl = 2.minutes
+
+Now, suppose we have another controller, `ArticlesController`, and we want to cache the `show` and `index` actions on it for a duration of 20 minutes. Simple!
+
+    Wallet.open do
+      cash :articles, :for => 20.minutes do
+        show
+        index
+      end
+    end
+
+This will cache only the `show` and `index` actions on the `ArticlesController`.
+
+Now imagine we've added a third action, `comments`, to our `ArticlesController`, and we want to cache it for only 1 minute:
+
+    Wallet.open do
+      cash :articles, :for => 20.minutes do
+        show
+        index
+        comments 1.minute
+      end
+    end
+
+## Before filters and action caching
+
+Sometimes, even though an action is cached, you want a before filter to run before Rails try's to serve out the cached response. Authentication is one common use case. You can accomplish this with Wallet by simply calling `cash!` after the before filters:
+
+    class ApplicationController < ActionController::Base
+      include Wallet::Cash
+
+      before_filter :authentication
+      cash!
+
+      private
+      def authentication
+        #...
+      end
+    end
+
+Now, the `authentication` method will run before your before filters. 
+
+## Engines
+
+Wallet plays nice with engines. If you'd like to use Wallet inside your engine, create a `config/wallet.rb` file inside your engine, then include `Wallet::Railtie` inside your Engine railtie:
+
+module Comments
+  class Engine < Rails::Engine
+    include Wallet::Railtie
+  end
+end
+
+Now, Rails will load the `config/wallet.rb` inside your engine before your controllers load.
