-The `Name` method is useful for error reporting. For example, if your shortcode requires a "greeting" parameter:
-
-{{< code file=layouts/shortcodes/myshortcode.html  >}}
-{{ $greeting := "" }}
-{{ with .Get "greeting" }}
-  {{ $greeting = . }}
-{{ else }}
-  {{ errorf "The %q shortcode requires a 'greeting' parameter. See %s" .Name .Position }}
-{{ end }}
-{{< /code >}}
-
-In the absence of a "greeting" parameter, Hugo will throw an error message and fail the build:
-
-```text
-ERROR The "myshortcode" shortcode requires a 'greeting' parameter. See "/home/user/project/content/about.md:11:1"
-```
