 ### When to use an index route
 
 The index route is most helpful for rendering a view when the route has [dynamic segments](#toc_dynamic-segments) defined in it or there are nested routes. In other words, an `index` template is used to show content that should not be present on sibling and child routes. For example, a blog app might have an `index` route that shows a list of all posts, but if a user clicks on a post, they should only see the content for the individual post. Here is how that looks in practice:

 When you provide a string or number to the `<LinkTo>`, the dynamic segment's `model` hook will run when the app transitions to the new route.
 In this example, `photo.id` might have an id of `4`:
 
-```handlebars {data-filename=app/templates/photos.hbs}
-{{#each @model as |photo|}}
-  <LinkTo @route="photo" @model={{photo.id}}>
-    link text to display
-  </LinkTo>
-{{/each}}
+```handlebars {data-filename=app/templates/photos.gjs}
+import { LinkTo } from '@ember/routing';
+
+<template>
+  {{#each @model as |photo|}}
+    <LinkTo @route="photo" @model={{photo.id}}>
+      link text to display
+    </LinkTo>
+  {{/each}}
+</template>
 ```
 
 However, if you provide the entire model context, the model hook for that URL segment will _not_ be run.
 For this reason, many Ember developers choose to pass only ids to `<LinkTo>` so that the behavior is consistent.
 
 Here's what it looks like to pass the entire `photo` record:
 
-```handlebars {data-filename=app/templates/photos.hbs}
-{{#each @model as |photo|}}
-  <LinkTo @route="photo" @model={{photo}}>
-    link text to display
-  </LinkTo>
-{{/each}}
+```handlebars {data-filename=app/templates/photos.gjs}
+import { LinkTo } from '@ember/routing';
+
+<template>
+  {{#each @model as |photo|}}
+    <LinkTo @route="photo" @model={{photo}}>
+      link text to display
+    </LinkTo>
+  {{/each}}
+</template>
 ```
 
 If you decide to pass the entire model, be sure to cover this behavior in your [application tests](../../testing/testing-application/).
 
 If a route you are trying to link to has multiple dynamic segments, like `/photos/4/comments/18`, be sure to specify all the necessary information for each segment:
