 Put this into your `.rubocop.yml`.
 
 ```yaml
-require: rubocop-rake
+plugins: rubocop-rake

 Alternatively, use the following array notation when specifying multiple extensions.
 
 ```yaml
-require:
+plugins:
   - rubocop-other-extension
   - rubocop-rake
 ```
 
 Now you can run `rubocop` and it will automatically load the RuboCop Rake
 cops together with the standard cops.
