 #### Angular.js dependency injection
 
-This is how it looks everywhere in the Angular.js code:
+Angular will automatically pass the services demanded by controllers, see https://docs.angularjs.org/guide/di

+Do this (inline array annotation):
 
 ```js
 controller: [
   "$scope",
-  "$rootScope",
-  "backend",
-  ($scope, $rootScope, backend) => {
-    ...
-  }
+  function ($scope) { ... }
 ]
 ```
 
-The variables of the controller is created automatically by Angular.js and "injected". When reading documenation online you can find the alternative:
+Do not do (implicit annotation):
 
 ```js
-controller: ($scope, $rootScope, backend) => {
-  ...
-}
+controller: function ($scope) { ... }

-But this doesn't work in Korp (anymore). Due to minification done by Webpack when building the frontend (`yarn build`). It probably works with `yarn start`, so beware.
