+The `Name` method is useful for error reporting. For example, if your shortcode requires a "greeting" parameter:
+
+{{< code file="layouts/shortcodes/myshortcode.html" lang=go-html-template copy=false >}}
+{{ $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"
+```
