+ 3. You can either move it manually or the following:
 
  ```shell
  mv app/controllers/movies_controller.rb app/controllers/api/v1
  ``` 
+ 4. Update the Movies Controller
+ 
+ Our newly generated controller does not properly inherit from the namespace api/v1 (We will update the routes later in the tutorial) so let's change our controller class from
 
+ ```ruby
+ class MoviesController < ApplicationController
+ ```
+ TO
+ 
+  ```ruby
+ class Api::V1::MoviesController < ApplicationController
+ ```
+ 
+5. Update the Routes 
+Locate to your config folder and open your ```routes.rb``` file.
+
+```ruby
+Rails.application.routes.draw do
+  resources :movies
+end
+```
+
+If we go to ```localhost:3000/movies``` we will not call the controller. We must update our Routes to:
+```ruby
+Rails.application.routes.draw do
+ namespace :api do
+  namespace :v1 do
+   resources :movies
+  end
+ end
+end
+```
+which allows us to call the json data from ```ruby localhost:3000/api/v1/movies```
