+The `Aliases` method on a `Page` object returns the URL [aliases] as defined in front matter.
+
+For example:
+
+{{< code-toggle file=content/about.md fm=true >}}
+title = 'About'
+aliases = ['/old-url','/really-old-url']
+{{< /code-toggle >}}
+
+To list the aliases:
+
+```go-html-template
+{{ range .Aliases }}
+  {{ . }}
+{{ end }}
+```
