+A chunk name from auto generated file can be conflicted with your code. You may see the below error log in that case:
+
+```
+ ERROR Failed to compile with 1 errors
+ error in ./node_modules/vue-auto-routing/index.js
+It's not allowed to load an initial chunk on demand. The chunk name "index" is already used by an entrypoint.
+ ERROR Build failed with errors.
+error Command failed with exit code 1.
+```
 
-You can specify options for this plugin under `pluginOptions.autoRouting` in `vue.config.js`.
+To avoid this error, you can set `chunkNamePrefix` option to change the auto generated chunk name.
 
 ```js
 // vue.config.js
 
 module.exports = {
  pluginOptions: {
  autoRouting: {
- // Specify vue-cli-plugin-auto-routing options here
+ // Specify a prefix which will be added to all auto generated chunk name.
  chunkNamePrefix: 'page-'
  }
  }
 }
 ```

+```js
+// vue.config.js
+
+module.exports = {
+ pluginOptions: {
+ autoRouting: {
+ // Specify vue-auto-routing options here
+ nested: false
+ }
+ }
+}
