 # Omniauth::MultipleProviders
 
-Good parts for Omniauth and Multiple Providers.
+Support for Omniauth and Multiple Providers.
 
+## Dependency
+
+### Devise
+
+Omniauth::MultipleProviders requires `User` model and `current_user` helper,  like Devise.
+You should create User model, before `rails g omniauth:multiple_providers:install`.
+ex) do `rails g devise User`
+
+### Omniauth and Omniauth Strategy
+
+You should setup Omniauth configuration, before `rails g omniauth:multiple_providers:install`.
+ex) create config/initializers/omniauth.rb file.
+
+``` ruby
+gem 'devise'
+gem 'omniauth'
+gem 'omniauth-facebook' # etc you needs
+gem 'omniauth-twitter'  # etc you needs
+```
+
 ## Installation
 
 Add this line to your application's Gemfile:
 
-    gem 'omniauth'
-    gem 'omniauth-facebook' # etc you needs
-    gem 'omniauth-twitter'  # etc you needs
-    # ...
-    gem 'omniauth-multiple_providers'
+``` ruby
+gem 'omniauth'
+gem 'omniauth-facebook' # etc you needs
+# ...
+gem 'omniauth-multiple_providers'
+```
 
 And then execute:
 
     $ bundle
 
 Or install it yourself as:
 
     $ gem install omniauth-multiple_providers
 
+`app/models/user.rb` (generated by Devise) do not use `:omniauthable`.
+
+``` ruby
+# app/models/user.rb
+class User < ActiveRecord::Base
+  # Include default devise modules. Others available are:
+  # :token_authenticatable, :confirmable,
+  # :lockable, :timeoutable and :omniauthable # <= do not use
+  devise :database_authenticatable, :registerable,
+         :recoverable, :rememberable, :trackable, :validatable, :confirmable
+  # ...
+end
+```
+
+``` sh
+$ rails generate omniauth:multiple_providers:install
+$ rake db:migrate # => create provider_users table
+```
+
 ## Usage
 
-    $ rails generate omniauth:multiple_providers:install
-    $ rake db:migrate # => create provider_users table
+You can use `new_omniauth_path(provider: :provider_name)`, and It redirect_to `/auth/:provider_name`.
+And automatically receive callback, and Save to `ProviderUser`(app/models/provider_user.rb).
+
+``` haml
+%ul
+  %li
+    = link_to new_omniauth_path(provider: :twitter), 'data-no-turbolink' => true do
+      Signup with Twitter
+  %li
+    = link_to new_omniauth_path(provider: :facebook), 'data-no-turbolink' => true do
+      Signup with Facebook
+  %li
+    = link_to new_omniauth_path(provider: :github), 'data-no-turbolink' => true do
+      Signup with Github
+```
+
+And if you remove connection to Providers,
+
+``` ruby
+= link_to omniauth_path(:twitter), method: :delete do
+  cancel connection
+```
