+The following shows `after` being used in conjunction with the [`slice`]function:
+
+```go-html-template
+{{ $data := slice "one" "two" "three" "four" }}
+<ul>
+  {{ range after 2 $data }}
+    <li>{{ . }}</li>
+  {{ end }}
+</ul>
+```
+
+The template above is rendered to:
+
+```html
+<ul>
+  <li>three</li>
+  <li>four</li>
+</ul>
+```
+
+## Example of `after` with `first`: 2nd&ndash;4th most recent articles
+
+You can use `after` in combination with the [`first`] function and Hugo's [powerful sorting methods][lists]. Let's assume you have a list page at `example.com/articles`. You have 10 articles, but you want your templating for the [list/section page] to show only two rows:
+
+1. The top row is titled "Featured" and shows only the most recently published article (i.e. by `publishdate` in the content files' front matter).
+2. The second row is titled "Recent Articles" and shows only the 2nd- to 4th-most recently published articles.
+
+{{< code file=layouts/section/articles.html >}}
+{{ define "main" }}
+  <section class="row featured-article">
+    <h2>Featured Article</h2>
+    {{ range first 1 .Pages.ByPublishDate.Reverse }}
+    <header>
+      <h3><a href="{{ .RelPermalink }}">{{ .Title }}</a></h3>
+    </header>
+    <p>{{ .Description }}</p>
+  {{ end }}
+  </section>
+  <div class="row recent-articles">
+    <h2>Recent Articles</h2>
+    {{ range first 3 (after 1 .Pages.ByPublishDate.Reverse) }}
+      <section class="recent-article">
+        <header>
+          <h3><a href="{{ .RelPermalink }}">{{ .Title }}</a></h3>
+        </header>
+        <p>{{ .Description }}</p>
+      </section>
+    {{ end }}
+  </div>
+{{ end }}
+{{< /code >}}
