+
+# Configuration
+
+VitePress configuration is defined in `.vitepress/config.[js|ts|mjs|mts]`. Use `defineConfig` for TypeScript intellisense.
+
+## Basic Config
+
+```ts
+// .vitepress/config.ts
+import { defineConfig } from 'vitepress'
+
+export default defineConfig({
+  // Site metadata
+  title: 'My Docs',
+  description: 'Documentation site',
+  lang: 'en-US',
+  
+  // URL base path (for GitHub Pages: '/repo-name/')
+  base: '/',
+  
+  // Theme configuration
+  themeConfig: {
+    // See theme-config.md
+  }
+})
+```
+
+## Site Metadata
+
+```ts
+export default defineConfig({
+  title: 'VitePress',           // Displayed in nav, used in page titles
+  titleTemplate: ':title - Docs', // Page title format (:title = h1)
+  description: 'Site description', // Meta description
+  lang: 'en-US',                 // HTML lang attribute
+  
+  head: [
+    ['link', { rel: 'icon', href: '/favicon.ico' }],
+    ['meta', { name: 'theme-color', content: '#5f67ee' }],
+    ['script', { async: '', src: 'https://analytics.example.com/script.js' }]
+  ]
+})
+```
+
+## Build Options
+
+```ts
+export default defineConfig({
+  // Source files directory (relative to project root)
+  srcDir: './src',
+  
+  // Exclude patterns from source
+  srcExclude: ['**/README.md', '**/TODO.md'],
+  
+  // Output directory
+  outDir: './.vitepress/dist',
+  
+  // Cache directory
+  cacheDir: './.vitepress/cache',
+  
+  // Clean URLs without .html extension (requires server support)
+  cleanUrls: true,
+  
+  // Ignore dead links during build
+  ignoreDeadLinks: true,
+  // Or specific patterns:
+  ignoreDeadLinks: ['/playground', /^https?:\/\/localhost/],
+  
+  // Get last updated timestamp from git
+  lastUpdated: true
+})
+```
+
+## Route Rewrites
+
+Map source paths to different output paths:
+
+```ts
+export default defineConfig({
+  rewrites: {
+    // Static mapping
+    'packages/pkg-a/src/index.md': 'pkg-a/index.md',
+    
+    // Dynamic parameters
+    'packages/:pkg/src/:slug*': ':pkg/:slug*'
+  }
+})
+```
+
+## Appearance (Dark Mode)
+
+```ts
+export default defineConfig({
+  appearance: true,           // Enable toggle (default)
+  appearance: 'dark',         // Dark by default
+  appearance: 'force-dark',   // Always dark, no toggle
+  appearance: 'force-auto',   // Always follow system preference
+  appearance: false           // Disable dark mode
+})
+```
+
+## Vite & Vue Configuration
+
+```ts
+export default defineConfig({
+  // Pass options to Vite
+  vite: {
+    plugins: [],
+    resolve: { alias: {} },
+    css: { preprocessorOptions: {} }
+  },
+  
+  // Pass options to @vitejs/plugin-vue
+  vue: {
+    template: { compilerOptions: {} }
+  },
+  
+  // Configure markdown-it
+  markdown: {
+    lineNumbers: true,
+    toc: { level: [1, 2, 3] },
+    math: true, // Requires markdown-it-mathjax3
+    container: {
+      tipLabel: 'TIP',
+      warningLabel: 'WARNING',
+      dangerLabel: 'DANGER'
+    }
+  }
+})
+```
+
+## Build Hooks
+
+```ts
+export default defineConfig({
+  // Transform page data
+  transformPageData(pageData, { siteConfig }) {
+    pageData.frontmatter.head ??= []
+    pageData.frontmatter.head.push([
+      'meta', { name: 'og:title', content: pageData.title }
+    ])
+  },
+  
+  // Transform head before generating each page
+  async transformHead(context) {
+    return [['meta', { name: 'custom', content: context.page }]]
+  },
+  
+  // After build completes
+  async buildEnd(siteConfig) {
+    // Generate sitemap, RSS, etc.
+  }
+})
+```
+
+## Dynamic Config
+
+For async configuration:
+
+```ts
+export default async () => {
+  const data = await fetch('https://api.example.com/data').then(r => r.json())
+  
+  return defineConfig({
+    title: data.title,
+    themeConfig: {
+      sidebar: data.sidebar
+    }
+  })
+}
+```
+
+## Key Points
+
+- Config file supports `.js`, `.ts`, `.mjs`, `.mts` extensions
+- Use `defineConfig` for TypeScript support
+- `base` must start and end with `/` for sub-path deployments
+- `srcDir` separates source files from project root
+- Build hooks enable custom transformations and post-processing
