+# TypeScript Declaration Files
+
+Generate `.d.ts` type declaration files for your library.
+
+## Overview
+
+tsdown uses [rolldown-plugin-dts](https://github.com/sxzz/rolldown-plugin-dts) to generate and bundle TypeScript declaration files.
+
+**Requirements:**
+- TypeScript must be installed in your project
+
+## Enabling DTS Generation
+
+### Auto-Enabled
+
+DTS generation is **automatically enabled** if `package.json` contains:
+- `types` field, or
+- `typings` field
+
+### Manual Enable
+
+#### CLI
+
+```bash
+tsdown --dts
+```
+
+#### Config File
+
+```ts
+export default defineConfig({
+  dts: true,
+})
+```
+
+## Performance
+
+### With `isolatedDeclarations` (Recommended)
+
+**Extremely fast** - uses oxc-transform for generation.
+
+```json
+// tsconfig.json
+{
+  "compilerOptions": {
+    "isolatedDeclarations": true
+  }
+}
+```
+
+### Without `isolatedDeclarations`
+
+Falls back to TypeScript compiler. Reliable but slower.
+
+## Declaration Maps
+
+Map `.d.ts` files back to original `.ts` sources (useful for monorepos).
+
+### Enable in tsconfig.json
+
+```json
+{
+  "compilerOptions": {
+    "declarationMap": true
+  }
+}
+```
+
+### Enable in tsdown Config
+
+```ts
+export default defineConfig({
+  dts: {
+    sourcemap: true,
+  },
+})
+```
+
+## Advanced Options
+
+### Custom Compiler Options
+
+Override TypeScript compiler options:
+
+```ts
+export default defineConfig({
+  dts: {
+    compilerOptions: {
+      removeComments: false,
+    },
+  },
+})
+```
+
+## Build Process
+
+- **ESM format**: `.js` and `.d.ts` files generated in same build
+- **CJS format**: Separate build process for `.d.ts` files
+
+## Common Patterns
+
+### Basic Library
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  dts: true,
+})
+```
+
+Output:
+- `dist/index.mjs`
+- `dist/index.cjs`
+- `dist/index.d.ts`
+
+### Multiple Entry Points
+
+```ts
+export default defineConfig({
+  entry: {
+    index: 'src/index.ts',
+    utils: 'src/utils.ts',
+  },
+  format: ['esm', 'cjs'],
+  dts: true,
+})
+```
+
+Output:
+- `dist/index.mjs`, `dist/index.cjs`, `dist/index.d.ts`
+- `dist/utils.mjs`, `dist/utils.cjs`, `dist/utils.d.ts`
+
+### With Monorepo Support
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  dts: {
+    sourcemap: true, // Enable declaration maps
+  },
+})
+```
+
+### Fast Build (Isolated Declarations)
+
+```json
+// tsconfig.json
+{
+  "compilerOptions": {
+    "isolatedDeclarations": true,
+    "declaration": true,
+    "declarationMap": true
+  }
+}
+```
+
+```ts
+// tsdown.config.ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  dts: true, // Will use fast oxc-transform
+})
+```
+
+## Troubleshooting
+
+### Missing Types
+
+Ensure TypeScript is installed:
+
+```bash
+pnpm add -D typescript
+```
+
+### Slow Generation
+
+Enable `isolatedDeclarations` in `tsconfig.json` for faster builds.
+
+### Declaration Errors
+
+Check that all exports have explicit types (required for `isolatedDeclarations`).
+
+### Report Issues
+
+For DTS-specific issues, report to [rolldown-plugin-dts](https://github.com/sxzz/rolldown-plugin-dts/issues).
+
+### Vue Support
+
+Enable Vue component type generation (requires `vue-tsc`):
+
+```ts
+export default defineConfig({
+  dts: {
+    vue: true,
+  },
+})
+```
+
+### Oxc Transform
+
+Control Oxc usage for declaration generation:
+
+```ts
+export default defineConfig({
+  dts: {
+    oxc: true,  // Use oxc-transform (fast, requires isolatedDeclarations)
+  },
+})
+```
+
+### Custom TSConfig
+
+Specify a different tsconfig for DTS generation:
+
+```ts
+export default defineConfig({
+  dts: {
+    tsconfig: './tsconfig.build.json',
+  },
+})
+```
+
+## Available DTS Options
+
+| Option | Type | Description |
+|--------|------|-------------|
+| `sourcemap` | `boolean` | Generate declaration source maps |
+| `compilerOptions` | `object` | Override TypeScript compiler options |
+| `vue` | `boolean` | Enable Vue type generation (requires vue-tsc) |
+| `oxc` | `boolean` | Use oxc-transform for fast generation |
+| `tsconfig` | `string` | Path to tsconfig file |
+| `resolver` | `'oxc' \| 'tsc'` | Module resolver: `'oxc'` (default, fast) or `'tsc'` (more compatible) |
+| `cjsDefault` | `boolean` | CJS default export handling |
+| `sideEffects` | `boolean` | Preserve side effects in declarations |
+
+## Tips
+
+1. **Always enable DTS** for TypeScript libraries
+2. **Use isolatedDeclarations** for fast builds
+3. **Enable declaration maps** in monorepos
+4. **Ensure explicit types** for all exports
+5. **Install TypeScript** as dev dependency
