+
+Use this function with both monolingual and multilingual configurations. The URL returned by this function depends on:
+
+- Whether the input begins with a slash
+- The `baseURL` in site configuration
+- The language prefix, if any
+
+In examples that follow, the project is multilingual with content in both Español (`es`) and English (`en`). The default language is Español. The returned values are from the English site.
+
+### Input does not begin with a slash
+
+If the input does not begin with a slash, the resulting URL will be correct regardless of the `baseURL`.
+
+With `baseURL = https://example.org/`
+
+```go-html-template
+{{ absLangURL "" }}           →   https://example.org/en/
+{{ absLangURL "articles" }}   →   https://example.org/en/articles
+{{ absLangURL "style.css" }}  →   https://example.org/en/style.css
+```
+
+With `baseURL = https://example.org/docs/`
+
+```go-html-template
+{{ absLangURL "" }}           →   https://example.org/docs/en/
+{{ absLangURL "articles" }}   →   https://example.org/docs/en/articles
+{{ absLangURL "style.css" }}  →   https://example.org/docs/en/style.css
+```
+
+### Input begins with a slash
+
+If the input begins with a slash, the resulting URL will be incorrect when the `baseURL` includes a subdirectory. With a leading slash, the function returns a URL relative to the protocol+host section of the `baseURL`.
+
+With `baseURL = https://example.org/`
+
+```go-html-template
+{{ absLangURL "/" }}          →   https://example.org/en/
+{{ absLangURL "/articles" }}  →   https://example.org/en/articles
+{{ absLangURL "/style.css" }} →   https://example.org/en/style.css
+```
+
+With `baseURL = https://example.org/docs/`
+
+```go-html-template
+{{ absLangURL "/" }}          →   https://example.org/en/
+{{ absLangURL "/articles" }}  →   https://example.org/en/articles
+{{ absLangURL "/style.css" }} →   https://example.org/en/style.css
+```
+
+{{% note %}}
+The last three examples are not desirable in most situations. As a best practice, never include a leading slash when using this function.
