+## Recent Updates
+
+### ESLint Configuration
+
+The ESLint configuration has been updated to use [@antfu/eslint-config](https://github.com/antfu/eslint-config) instead of @shopify/eslint-plugin. This change brings several benefits:
+
+- Uses the new ESLint flat config format
+- Provides better TypeScript support
+- Includes sensible defaults for modern JavaScript/TypeScript development
+- Simplified configuration with a unified approach
+
+See the [eslint-plugin README](packages/eslint-plugin/README.md) for more details on usage.
+
 ### Releasing
 
 Everything is automated with `auto` and Github Actions

+Opinionated eslint configuration based on [@antfu/eslint-config](https://github.com/antfu/eslint-config)
 
 ## Installation
 
@@ -21,17 +21,41 @@ $ npm install --save-dev @bepower/eslint-plugin
 
 ## Usage
 
-`.eslintrc.json` or `"eslintConfig"` property inside `package.json`
+Create an `eslint.config.js` file in the root of your project:
+
+```js
+import { bePowerFactory } from '@bepower/eslint-plugin';
+
+export default [
+  ...bePowerFactory({
+    // Options (all default to these values except cdk)
+    cdk: false,      // Set to true for AWS CDK projects
+    node: true,      // Node.js environment
+    typescript: true, // TypeScript support
+    react: false,    // React support
+  }),
+  // Add your custom configurations here
+];
+```
+
+### Quick Setup
 
-```json
-{
-  "extends": "plugin:@bepower/node",
-  "parserOptions": {
-    "project": "./tsconfig.json"
-  }
-}
+You can also use the CLI to generate a basic configuration:
+
+```bash
+$ npx @bepower/eslint-plugin config:init
 ```
 
+## Features
+
+- Based on [@antfu/eslint-config](https://github.com/antfu/eslint-config)
+- Uses the new ESLint flat config format
+- Includes sensible defaults for TypeScript and Node.js projects
+- Optional support for React and AWS CDK projects
+- Stylistic rules with semicolons and 1tbs brace style
+
