```go-html-template
{{ ref . "about" }}
{{ ref . "about#anchor" }}
{{ ref . "about.md" }}
{{ ref . "about.md#anchor" }}
{{ ref . "#anchor" }}
{{ ref . "/blog/my-post" }}
{{ ref . "/blog/my-post.md" }}
```

```go-html-template
{{ ref . (dict "path" "about.md" "lang" "fr") }}
```

Hugo emits an error or warning if the page cannot be uniquely resolved. The error behavior is configurable; see [Ref and RelRef Configuration](/content-management/cross-references/#ref-and-relref-configuration).
This function is used by Hugo's built-in [`ref`](/content-management/shortcodes/#ref-and-relref) shortcode. For a detailed explanation of how to leverage this shortcode for content management, see [Links and Cross References](/content-management/cross-references/).
