+# Customizing Rolldown Options
+
+Pass options directly to the underlying Rolldown bundler.
+
+## Overview
+
+tsdown uses [Rolldown](https://rolldown.rs) as its core bundling engine. You can override Rolldown's input and output options directly for fine-grained control.
+
+**Warning:** You should be familiar with Rolldown's behavior before overriding options. Refer to the [Rolldown Config Options](https://rolldown.rs/options/input) documentation.
+
+## Input Options
+
+### Using an Object
+
+```ts
+export default defineConfig({
+  inputOptions: {
+    cwd: './custom-directory',
+  },
+})
+```
+
+### Using a Function
+
+Dynamically modify options based on the output format:
+
+```ts
+export default defineConfig({
+  inputOptions(inputOptions, format) {
+    inputOptions.cwd = './custom-directory'
+    return inputOptions
+  },
+})
+```
+
+## Output Options
+
+### Using an Object
+
+```ts
+export default defineConfig({
+  outputOptions: {
+    legalComments: 'inline',
+  },
+})
+```
+
+### Using a Function
+
+```ts
+export default defineConfig({
+  outputOptions(outputOptions, format) {
+    if (format === 'esm') {
+      outputOptions.legalComments = 'inline'
+    }
+    return outputOptions
+  },
+})
+```
+
+## Common Use Cases
+
+### Preserve Legal Comments
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  outputOptions: {
+    legalComments: 'inline',
+  },
+})
+```
+
+### Custom Working Directory
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  inputOptions: {
+    cwd: './packages/my-lib',
+  },
+})
+```
+
+### Format-Specific Options
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  outputOptions(outputOptions, format) {
+    if (format === 'esm') {
+      outputOptions.legalComments = 'inline'
+    }
+    return outputOptions
+  },
+})
+```
+
+## When to Use
+
+- When tsdown doesn't expose a specific Rolldown option
+- For format-specific Rolldown customizations
+- For advanced bundling scenarios
+
+## Tips
+
+1. **Read Rolldown docs** before overriding options
+2. **Use functions** for format-specific customization
+3. **Test thoroughly** when overriding defaults
+4. **Prefer tsdown options** when available (e.g., use `minify` instead of setting it via `outputOptions`)
