+---
+
+# Internationalization
+
+VitePress supports multi-language sites through locale configuration.
+
+## Directory Structure
+
+Organize content by locale:
+
+```
+docs/
+├─ en/
+│  ├─ guide.md
+│  └─ index.md
+├─ zh/
+│  ├─ guide.md
+│  └─ index.md
+└─ fr/
+   ├─ guide.md
+   └─ index.md
+```
+
+Or with root as default language:
+
+```
+docs/
+├─ guide.md        # English (root)
+├─ index.md
+├─ zh/
+│  ├─ guide.md
+│  └─ index.md
+└─ fr/
+   ├─ guide.md
+   └─ index.md
+```
+
+## Configuration
+
+```ts
+// .vitepress/config.ts
+import { defineConfig } from 'vitepress'
+
+export default defineConfig({
+  locales: {
+    root: {
+      label: 'English',
+      lang: 'en'
+    },
+    zh: {
+      label: '简体中文',
+      lang: 'zh-CN',
+      link: '/zh/'
+    },
+    fr: {
+      label: 'Français',
+      lang: 'fr',
+      link: '/fr/'
+    }
+  }
+})
+```
+
+## Locale-Specific Config
+
+Override site config per locale:
+
+```ts
+locales: {
+  root: {
+    label: 'English',
+    lang: 'en',
+    title: 'My Docs',
+    description: 'Documentation site',
+    themeConfig: {
+      nav: [
+        { text: 'Guide', link: '/guide/' }
+      ],
+      sidebar: {
+        '/guide/': [
+          { text: 'Introduction', link: '/guide/' }
+        ]
+      }
+    }
+  },
+  zh: {
+    label: '简体中文',
+    lang: 'zh-CN',
+    link: '/zh/',
+    title: '我的文档',
+    description: '文档站点',
+    themeConfig: {
+      nav: [
+        { text: '指南', link: '/zh/guide/' }
+      ],
+      sidebar: {
+        '/zh/guide/': [
+          { text: '介绍', link: '/zh/guide/' }
+        ]
+      }
+    }
+  }
+}
+```
+
+## Locale-Specific Properties
+
+Each locale can override:
+
+```ts
+interface LocaleSpecificConfig {
+  lang?: string
+  dir?: string              // 'ltr' or 'rtl'
+  title?: string
+  titleTemplate?: string | boolean
+  description?: string
+  head?: HeadConfig[]       // Merged with existing
+  themeConfig?: ThemeConfig // Shallow merged
+}
+```
+
+## Search i18n
+
+### Local Search
+
+```ts
+themeConfig: {
+  search: {
+    provider: 'local',
+    options: {
+      locales: {
+        zh: {
+          translations: {
+            button: {
+              buttonText: '搜索',
+              buttonAriaLabel: '搜索'
+            },
+            modal: {
+              noResultsText: '没有结果',
+              resetButtonTitle: '重置搜索',
+              footer: {
+                selectText: '选择',
+                navigateText: '导航',
+                closeText: '关闭'
+              }
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+### Algolia Search
+
+```ts
+themeConfig: {
+  search: {
+    provider: 'algolia',
+    options: {
+      appId: '...',
+      apiKey: '...',
+      indexName: '...',
+      locales: {
+        zh: {
+          placeholder: '搜索文档',
+          translations: {
+            button: { buttonText: '搜索文档' }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+## Separate Locale Directories
+
+For fully separated locales without root fallback:
+
+```
+docs/
+├─ en/
+│  └─ index.md
+├─ zh/
+│  └─ index.md
+└─ fr/
+   └─ index.md
+```
+
+Requires server redirect for `/` → `/en/`. Netlify example:
+
+```
+/* /en/:splat 302 Language=en
+/* /zh/:splat 302 Language=zh
+/* /en/:splat 302
+```
+
+## Persisting Language Choice
+
+Set cookie on language change:
+
+```vue
+<!-- .vitepress/theme/Layout.vue -->
+<script setup>
+import DefaultTheme from 'vitepress/theme'
+import { useData, inBrowser } from 'vitepress'
+import { watchEffect } from 'vue'
+
+const { lang } = useData()
+
+watchEffect(() => {
+  if (inBrowser) {
+    document.cookie = `nf_lang=${lang.value}; expires=Mon, 1 Jan 2030 00:00:00 UTC; path=/`
+  }
+})
+</script>
+
+<template>
+  <DefaultTheme.Layout />
+</template>
+```
+
+## RTL Support (Experimental)
+
+For right-to-left languages:
+
+```ts
+locales: {
+  ar: {
+    label: 'العربية',
+    lang: 'ar',
+    dir: 'rtl'
+  }
+}
+```
+
+Requires PostCSS plugin like `postcss-rtlcss`:
+
+```ts
+// postcss.config.js
+import rtlcss from 'postcss-rtlcss'
+
+export default {
+  plugins: [
+    rtlcss({
+      ltrPrefix: ':where([dir="ltr"])',
+      rtlPrefix: ':where([dir="rtl"])'
+    })
+  ]
+}
+```
+
+## Organizing Config
+
+Split config into separate files:
+
+```
+.vitepress/
+├─ config/
+│  ├─ index.ts      # Main config, merges locales
+│  ├─ en.ts         # English config
+│  ├─ zh.ts         # Chinese config
+│  └─ shared.ts     # Shared config
+```
+
+```ts
+// .vitepress/config/index.ts
+import { defineConfig } from 'vitepress'
+import { shared } from './shared'
+import { en } from './en'
+import { zh } from './zh'
+
+export default defineConfig({
+  ...shared,
+  locales: {
+    root: { label: 'English', ...en },
+    zh: { label: '简体中文', ...zh }
+  }
+})
+```
+
+## Key Points
+
+- Use `locales` object in config with `root` for default language
+- Each locale can override title, description, and themeConfig
+- `themeConfig` is shallow merged (define complete nav/sidebar per locale)
+- Don't override `themeConfig.algolia` at locale level
+- `dir: 'rtl'` enables RTL with PostCSS plugin
+- Language switcher appears automatically in nav
