+It provides:

+- Translation strings for default values (English and French). Feel free to contribute !
+- Automatic menu generation from multilingual content
+- In-browser language switching
+
+![I18n menu](/en/cont/i18n/images/i18n-menu.gif)
+
+## Basic configuration
+
+After learning [how Hugo handle multilingual websites](https://gohugo.io/content-management/multilingual), define your languages in your `config.toml` file.
+
+For example with current French and English website.
+
+```toml
+# English is the default language
+defaultContentLanguage = "en"
+# Force to have /en/my-page and /fr/my-page routes, even for default language.
+defaultContentLanguageInSubdir= true
+
+[Languages]
+[Languages.en]
+title = "Documentation for Hugo Learn Theme"
+weight = 1
+languageName = "English"
+
+[Languages.fr]
+title = "Documentation du thème Hugo Learn"
+weight = 2
+languageName = "Français"
+```
+
+Then, for each new page, append the *id* of the language to the file.
+
+- Single file `my-page.md` is split in two files:
+    - in English: `my-page.en.md`
+    - in French: `my-page.fr.md`
+- Single file `_index.md` is split in two files:
+    - in English: `_index.en.md`
+    - in French: `_index.fr.md`
+
+{{% notice info %}}
+Be aware that only translated pages are displayed in menu. It's not replaced with default language content.
+{{% /notice %}}
+
+{{% notice tip %}}
+Use [slug](https://gohugo.io/content-management/multilingual/#translate-your-content) Front Matter parameter to translate urls too.
+{{% /notice %}}
+
+## Overwrite translation strings
+
+Translations strings are used for common default values used in the theme (*Edit this page* button, *Search placeholder* and so on). Translations are available in french and english but you may use another language or want to override default values.
+
+To override these values, create a new file in your local i18n folder `i18n/<idlanguage>.toml` and inspire yourself from the theme `themes/hugo-theme-learn/i18n/en.toml` 
+
+By the way, as these translations could be used by other people, please take the time to propose a translation by [making a PR](https://github.com/matcornic/hugo-theme-learn/pulls) to the theme ! 
+
+## Disable language switching
+
+Switching the language in the browser is a great feature, but for some reasons you may want to disable it. 
+
+Just set `disableLanguageSwitchingButton=true` in your `config.toml`
+
+```toml
+[params]
+  # When using mulitlingual website, disable the switch language button.
+  disableLanguageSwitchingButton = true
+```
