+
+[Boulangerie] is a Ruby gem for building authorization systems using
+[Macaroons](http://macaroons.io), a better kind of cookie.
+
+[Boulangerie]: https://github.com/cryptosphere/boulangerie
+
+## Installation
+
+boulangerie-rails can be used with Rails 4.1+.
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'boulangerie-rails'
+```
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install boulangerie-rails
+
+## Usage
+
+Add the following to `config/initializers/boulangerie.rb`:
+
+```ruby
+Boulangerie.setup(
+  schema:   Rails.root.join("config/boulangerie_schema.yml"),
+  keys:     Rails.application.secrets.boulangerie_keys
+  key_id:   "key1"
+  location: "https://mycoolsite.com"
+)
+```
+
+You will also need to edit `config/secrets.yml` and add the following to
+your respective environments (example given for development):
+
+```yaml
+development:
+  secret_key_base: DEADBEEFDEADBEEFDEADBEEF[...]
+  boulangerie_keys:
+    key0: "1b942ba242e9d39ce838d03652091695eb1fef93d35d9454498ca970a8827e8f"
+    key1: "7efc8f72d159ce31a4b2c8db6281bf8d91a2f2778d4d0062f80b977ea43a8ec4"
+```
+
+The `boulangerie_keys` hash contains a "keyring" of keys which can be used to
+create or verify Macaroons.
+
+To generate random keys, use the `Boulangerie::Keyring.generate_key` method,
+which you can call from `irb` or `pry`:
+
+```
+[1] pry(main)> require 'boulangerie'
+=> true
+[2] pry(main)> Boulangerie::Keyring.generate_key
+=> "1b942ba242e9d39ce838d03652091695eb1fef93d35d9454498ca970a8827e8f"
+```
+
+The names of the keys (e.g. `key0`, `key1`) are arbitrary, but all new Macaroons
+will use the key whose ID was passed in as the `key_id` option to
+`Boulangerie#initialize`. This allows for key rotation, i.e. periodically you can
+add a new key, and Macaroons minted under an old key will still verify.
+
+Rotating keys is good security practice and you should definitely take advantage of it.
+
+You'll also need to create a `config/boulangerie_schema.yml` file that
+contains the schema for your Macaroons. Here is a basic schema that will
+add `not-before` and `expires` timestamp assertions on your Macaroons:
+
+```yaml
+---
+schema-id: ee6da70e5ba01fec
+predicates:
+  v0:
+    not-before: DateTime
+    expires: DateTime
+```
+
+A `schema-id` is a 64-bit random number. This is used to identify a schema
+uniquely within your system regardless of what you decide to name or rename
+the schema file.
+
+You can generate a schema ID via `irb` or `pry`:
+
+```
+[1] pry(main)> require 'boulangerie'
+=> true
+[2] pry(main)> Boulangerie::Schema.create_schema_id
+=> "ee6da70e5ba01fec"
+```
+
+A schema-id can also be any 64-bit random number serialized as hex which
+is unique to your app/infrastructure.
+
+This schema includes two *caveats*: an expiration date and a creation time,
+before which the Macaroon is not considered valid.
+The predicate matchers for these particular caveats are built into
+Boulangerie, but you can extend it with your own.
+
+To create a Macaroon, we'll need to call the `#bake` method. The following
+will create a new Macaroon and set it as the "my_macaroon" cookie:
+
+```ruby
+class AuthenticationController < ApplicationController
+  # Perform some kind of authentication ritual here
+  before_action :check_credentials, :only => :authenticate
+
+  def authenticate
+    expires_at = 24.hours.from_now
+
+    cookie = Boulangerie.bake(caveats: {
+      expires:    Time.now,
+      not_before: expires_at
+    })
+
+    cookies[:my_macaroon] = {
+      value:    cookie,
+      expires:  expires_at,
+      secure:   true,
+      httponly: true
+    }
+  end
+```
+
+Finally, to actually use Macaroons to make authorization decisions, we need
+to configure Boulangerie in a given controller:
+
+```ruby
+class MyController < ApplicationController
+  authorize_with_boulangerie :cookie => :my_macaroon
+end
+```
