+**Editor: type `*ngFor` on screen and do an X**
 
 - Angular 17 is shipped with a new control flow syntax and there is a better way to loop on iterables in your angular templates
 
-- In the new `@for` `track` is mandatory with a simpler api to optimize
+- So stop using *ngFor and instead use the new `@for` syntax in your angular templates
+**Editor: type `@for` and a v checkmark**
+
+There are benefits for using the new syntax:
+- better performance
+- easier to see the boundaries of the loop - **Editor should highlight the curly brackets**
+- track function is mandatory with an easier api - **Editor should highlight the track part**
+- Support for `@empty` block on edge cases where the iterable is empty null or undefined. - **Editor should highlight the empty block**
+
+Check out our complete `@for` guide and a coding playground to play with the new syntax
