-This verson is outdated and might leave you with outdated versions of this library and associated Webpack tooling.
-There's a [pending release](https://github.com/humanmade/webpack-helpers/pull/205) that will fix this problem. But for now you should install humanmade/webpack-helpers@beta, webpack @5, webpack-cli@4, and webpack-dev-server@4. To do so run the following command:

 **ESLint**
 
-If [ESLint](https://eslint.org/) is installed, `eslint-loader` will be used to validate that your code compiles and passes required style rules before the bundle is generated. While ESLint will be used if present, these helpers do not assume any specific configuration or rules. If you aren't using ESLint you may install and configure it with basic syntax and style rules by following the [official getting started guide](https://eslint.org/docs/user-guide/getting-started), or by installing Human Made's [`@humanmade/eslint-config`](https://www.npmjs.com/package/@humanmade/eslint-config) preset.
+If [ESLint](https://eslint.org/) is installed, the webpack plugin `eslint-webpack-plugin` will be used to validate that your code compiles and passes required style rules before the bundle is generated. This package now supports ESLint 9+ with the modern flat configuration format.
+
+To configure ESLint for your project, create an `eslint.config.js` file in your project root:
+
+```js
+// eslint.config.js
+import js from '@eslint/js';
+
+export default [
+  js.configs.recommended,
+  {
