+### Dealing with nested params
+
+Once `snake_eyes_params` has been enabled for a controllor, `params` accepts an options hash, which can be used to specify which attributes should have the `_attributes` suffix appended.
+
+ ```ruby
+ class WithoutSnakeEyesController < ApplicationController
+
+    def show
+       params # results in:
+       # {
+       #    'user' => {
+       #      'name' => 'John Smith',
+       #      'favouriteColor' => 'blue',
+       #      'address' => { '123 street' },
+       #      'billingAddress' => { '456 road' }
+       #    }
+       #}
+    end
+ end
+
+ class WithSnakeEyesController < ApplicationController
+     snake_eyes_params
+
+     def show
+        params(nested_attributes: { user: [ :address, :billing_address ] }) # results in:
+        # {
+        #    'user_attributes' => {
+        #      'name' => 'John Smith',
+        #      'favourite_color' => 'blue',
+        #      'address_attributes' => { '123 street' },
+        #      'billing_address_attributes' => { '456 road' }
+        #    }
+        #}
+     end
+  end
+ ```
+
+To specify nested objects that should not have the `_attributes` suffix (but contain attributes that should), you can prefix them with an underscore:
+
+
+```ruby
+ class WithSnakeEyesController < ApplicationController
+     snake_eyes_params
+
+     def show
+        params(nested_attributes: { _user: [ :address, :billing_address ] }) # results in:
+        # {
+        #    'user' => {
+        #      'name' => 'John Smith',
+        #      'favourite_color' => 'blue',
+        #      'address_attributes' => { '123 street' },
+        #      'billing_address_attributes' => { '456 road' }
+        #    }
+        #}
+     end
+  end
+ ```
 
 ## Configuration
 
 By default SnakeEyes logs the snake case parameters to the Rails console. You can prevent this behaviour by configuring the gem:
