+### LogoutRequest
+
+To generate a Response choose the desired binding form the metadata and
+use it to serialize a response. You will also need to specify a user
+object to create a response for.
+
+```ruby
+class User
+  attr_reader :id, :email
+
+  def initialize(id:, email:)
+    @id = id
+    @email = email
+  end
+
+  def name_id_for(name_id_format)
+    Saml::Kit::Namespaces::PERSISTENT == name_id_format ? id : email
+  end
+
+  def assertion_attributes_for(request)
+    request.trusted? ? { access_token: SecureRandom.uuid } : {}
+  end
+end
+
+user = User.new(id: SecureRandom.uuid, email: "hello@example.com")
