 - **Default:** `true`
 
 Whether to automatically externalize dependencies and do not bundle them.
+
+## autoExternal.dependencies
+
+- **Type:** `boolean`
+- **Default:** `true`
+
+Whether to externalize dependencies of type `dependencies`.
+
+## autoExternal.optionalDependencies
+
+- **Type:** `boolean`
+- **Default:** `true`
+
+Whether to externalize dependencies of type `optionalDependencies`.
+
+## autoExternal.peerDependencies
+
+- **Type:** `boolean`
+- **Default:** `true`
+
+Whether to externalize dependencies of type `peerDependencies`.
+
+## autoExternal.devDependencies
+
+- **Type:** `boolean`
+- **Default:** `false`
+
+Whether to bundle dependencies of type `devDependencies`.
+
+## Default Value
+
+The default value of `autoExternal` is `true`, which means the following dependency types will **not be bundled**:
+
+- `dependencies`
+- `optionalDependencies`
+- `peerDependencies`
+
+And the following dependency types will be **bundled**:
+
+- `devDependencies`
+
+It is equivalent to the following configuration:
+
+```ts
+export default {
+  lib: [
+    {
+      format: 'esm',
+      autoExternal: {
+        dependencies: true,
+        optionalDependencies: true,
+        peerDependencies: true,
+        devDependencies: false,
+      },
+    },
+  ],
+};
+```
+
+## Example
+
+### Customize Externalized Dependency Types
+
+To disable the processing of a specific type of dependency, you can configure `autoExternal` as an object like this:
+
+```ts title="rslib.config.ts"
+export default {
+  lib: [
+    {
+      format: 'esm',
+      autoExternal: {
+        dependencies: false,
+        peerDependencies: false,
+      },
+    },
+  ],
+};
+```
+
+### Disable Default Behavior
+
+If you want to disable the default behavior, you can set `autoExternal` to `false`:
+
+```ts title="rslib.config.ts"
+export default {
+  lib: [
+    {
+      format: 'esm',
+      autoExternal: false,
+    },
+  ],
+};
+```
