+    This snippet makes a list of links to the of children of the current page using an unordered HTML list.
 
-<ul>
-    @foreach (var item in selection)
-    {
-        <li><a href="@item.Url">@item.Name</a></li>
-    }
-</ul>
+    How it works:
+    - It uses the Children method to get all child pages
+    - It then uses the OrderByDescending() method, which takes the property to sort. In this case the page's creation date.
+    - It then generates links so the visitor can go to each page
