+We provided a CLI tool to help you set up your project, or migrate from the legacy config to the new flat config with one command.
 
 ```bash
 npx @antfu/eslint-config@latest

-### Install
+### Manual Install
+
+If you prefer to set up manually:
 
 ```bash
 pnpm i -D eslint @antfu/eslint-config
 ```
 
-### Create config file
-
-With [`"type": "module"`](https://nodejs.org/api/packages.html#type) in `package.json` (recommended):
+And create `eslint.config.mjs` in your project root:
 
 ```js
-// eslint.config.js
+// eslint.config.mjs
 import antfu from '@antfu/eslint-config'
 
 export default antfu()
 ```
 
-With CJS:
-
-```js
-// eslint.config.js
-const antfu = require('@antfu/eslint-config').default
-
-module.exports = antfu()
-```
-
-> [!TIP]
-> ESLint only detects `eslint.config.js` as the flat config entry, meaning you need to put `type: module` in your `package.json` or you have to use CJS in `eslint.config.js`. If you want explicit extension like `.mjs` or `.cjs`, or even `eslint.config.ts`, you can install [`eslint-ts-patch`](https://github.com/antfu/eslint-ts-patch) to fix it.

+If you still use some configs from the legacy eslintrc format, you can use the [`@eslint/eslintrc`](https://www.npmjs.com/package/@eslint/eslintrc) package to convert them to the flat config.
