 #### How to use custom parser?
 
-If you want to use custom parsers such as [babel-eslint](https://www.npmjs.com/package/babel-eslint) or [typescript-eslint-parser](https://www.npmjs.com/package/typescript-eslint-parser), you have to use `parserOptions.parser` option instead of `parser` option. Because this plugin requires [vue-eslint-parser](https://www.npmjs.com/package/vue-eslint-parser) to parse `.vue` files, so this plugin doesn't work if you overwrote `parser` option.
