+{{< code-toggle file=hugo >}}
+defaultContentLanguage = 'de'
+defaultContentLanguageInSubdir = false
+
+[languages.de]
+languageCode = 'de-DE'
+languageDirection = 'ltr'

+When visiting the German language site:
+
+```go-html-template
+{{ .Site.LanguagePrefix }} → ""
+```
+
+When visiting the English language site:
+
+```go-html-template
+{{ .Site.LanguagePrefix }} → /en
+```
+
+If you change `defaultContentLanguageInSubdir` to `true`, when visiting the German language site:
+
+```go-html-template
+{{ .Site.LanguagePrefix }} → /de
+```
+
+You may use the `LanguagePrefix` method with both monolingual and multilingual sites.
