 ## Information
 
+The View Transition API is a brand new API that provides a set of features that allow developers to control and manipulate the transitions and animations between views within an application.
+It plays a pivotal role in enhancing user experience (UX), bringing applications to life with engaging and captivating transitions to guide users through different pages or sections of the app.
+
+The goal of this challenge is to learn about and manipulate all types of transitions proposed by the API.
+
+To use the API, Angular provides a function `withViewTransitions()` that needs to be injected inside the router config.
+
+I would advise you to read the [Chrome documentation](https://developer.chrome.com/docs/web-platform/view-transitions). You will learn everything necessary to successfully complete the challenge.
+
+Here, however, is a short summary:
+Firstly, each target DOM element has two states; an `old` one when the element is leaving the page, and a `new` one when it's entering the page:
+
+```css
+::view-transition-old(root) {
+/ / animation
+}
+
+::view-transition-new(root) {
+/ / animation
+}
+```
+
+In order to target a specific element, you must add the selector `view-transition-name` to a CSS class on the DOM node, as shown below:
+
+```css
+.specific-element {
+  view-transition-name: specific-element;
+}
+```
+
+This allows you to create an animation for this element only.
+
+Lastly, if the same element is present in both views, you can automate the transition by assigning the same **transition name**.
+
+:::danger
+Remenber, you can have only ONE UNIQUE `view-transition-name` per page.
+:::
+
 ## Statement
 
-## Constraints
+The goal of this challenge is to transition from the state shown in this video:
+
+To the final state shown in the following video:
+
+Observe the following:
+
+- The header slides in and out
+- Each element smoothly transitions to its new location
+
+### Level 1
+
+Focus only on the first thumbnail and create a seamless and pleasing transition
+
+### Level 2
+
+Create the same appealing transition for all thumbnails without duplicating the `view-transition-name`. Note that this page has only 3 thumbnails; in a real-life scenario, you could have significantly more.
+
+### Level 3
+
+Shift to the correct Y location when navigating back and forth.
