- ## Minor changes
+## Angularjs requirement
+
+`ng-admin` does not include `angularjs` anymore.
+
+You must add `angularjs` library inclusion into your app index:
+
+```html
+<script src="/path/to/bower_components/angular/angular.min.js" type="text/javascript"></script>
+```
+
+## Minor changes
 
  - `value` is now a function so the value of a field should be retrieved with `views.getField('fieldName').value()` instead of `views.getField('fieldName').value`.
  - `callback` field type & method are now called `template`.
