+## Information
+
+In this application, we retrieve three pieces of information inside our `TestComponent` provided by the router:
+
+- We want to retrieve `testId` found inside the params of the URL.
+- We want to obtain `user` located within the query parameters of the URL.
+- We want to access `permission` set inside the `data` object of the route.
+
+In Angular versions 15 or earlier, we use `ActivatedRoute` to obtain all this information and receive them through observables to listen for URL changes.
+
+In version 16, Angular introduced a new `Input` that can listen to route data. You can read more about it [here](https://medium.com/ngconf/accessing-route-params-in-angular-1f8e12770617).

 ## Statement
 
-In this small application, you can pass data though routing to `TestComponent`. v16 of Angular introduiced `RouterInput`. The goal of this exercice is to refactor the code to use the new `RouterInput` strategy.
