 ## Usage
 
-### Devise >= 2.1.1
+Add `:async` to the `devise` call in your model:
 
-Include `Devise::Async::Model` to your Devise model
-
 ```ruby
 class User < ActiveRecord::Base
-  devise :database_authenticatable, :confirmable # etc ...
-
-  include Devise::Async::Model # should be below call to `devise`
+  devise :database_authenticatable, :async, :confirmable # etc ...
 end
 ```
 
+Set your queuing backend by creating `config/initializers/devise_async.rb`:
+
+```ruby
+# Supported options: :resque, :sidekiq, :delayed_job
+Devise::Async.backend = :resque
+```
+
+Tip: it defaults to Resque. You don't need to create the initializer if using it.
+
 ### Devise < 2.1.1
 
 Set `Devise::Async::Proxy` as Devise's mailer in `config/initializers/devise.rb`:
 
 ```ruby
 # Configure the class responsible to send e-mails.
 config.mailer = "Devise::Async::Proxy"
 ```
-### All
