+With Hugo i18n possibilities, you can easily have a website in your language. This Hugo theme is ready to be translated into other languages. You can create a special file that contains translated text to show the visitor instead of English.

+
+## Translating the Theme
+
+1. Create a folder named `/i18n/` in your Hugo site's root
+1. Create a file `<LANG-CODE>.yaml` inside `/i18n` folder. Language files `<LANG-CODE>.yaml` should be named according to RFC 5646 with names such as `en-US.yaml`, `fr.yaml`, `de.yaml`, etc.
+1. Copy a reference template to your translation from `<THEME>/i18n/en.yaml` file
+1. Translate all available `translation` strings into chosen language
+
+For example, to create German translation, create a file `/i18n/de.yaml` in the folder of your Hugo site, copy reference template from `<THEME>/i18n/en.yaml` file and translate all available `translation` strings.
+
+## Changing Site Language in Hugo
+
+To use the translations, just set a correct value for `defaultContentLanguage` in site config file:
+
+{{< highlight toml >}}
+defaultContentLanguage = "en" # de / fr / other lang code...
+{{< /highlight >}}
+
+In other words, this field determines which i18n file to use.
+
