+# Configster
+
+Configster is a tidy little configuration management utility for your application.
+
+You probably haven't heard of it.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'configster'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install configster
+
+## Usage
+
+For most applications, you'll want to load Configster before you start loading the rest of your application.  For example:
+
+    require 'configster'
+    Configster.load_configster!(File.join('path', 'to', 'my_config.yml'))
+
+You can also pass a raw hash of stuff into `load_configster!` as long as it's in the format of `"ClassName" => { 'variable' => 'whatever' }`
+
+Then, just include Configster in any classes you want:
+
+    class KonfiguredKlass
+      include Configster
+    end
+
+Your class now has access to a `configster` and `raw_configster` function where you can query bits and pieces of your configuration.
+
+## Example
+
+Say you're writing a sweet application that uses [HTTParty](https://github.com/jnunemaker/httparty) to fetch data from Twitter.  You want to share this application with the world, but you don't want to hard code your credentials.  Here's how you might handle that:
+
+First, make yourself a nice little configuration file and save it to `~/my_sweet_app_credentials.yml`:
+
+    MySweetApp:
+      username: SweetUsername
+      password: SweetPassword123
+      
+Then, you'll write your application like this:
+
+    require 'configster'
+    Configster.load_configster!('~/my_sweet_app_credentials.yml')
+
+    class MySweetApp
+
+      include Configster
+      include HTTParty
+      
+      def initialize
+        @auth = {
+          :username => configster.username,
+          :password => configster.password
+        }
+      end
+      
+      def timeline(which = :friends, options = { })
+        options.merge!(:basic_auth => @auth)
+        self.class.get("/statuses/#{which}_timeline.json", options)
+      end
+      
+    end
+
+Now you can share your application without hard coding and/or sharing your credentials.
+
+
