 ## Setting up ESLint rules
 
-ESLint may display many warnings and errors about your code when you start using it but don't let this startle you. To get started, create a file in your project directory named `.eslintrc.json` and copy the code below into the file:
+ESLint may display many warnings and errors about your code when you start using it but don't let this startle you. To get started, create a file in your project directory named `eslint.config.js` and copy the code below into the file:
 
-```json
-{
-	"extends": "eslint:recommended",
-	"env": {
-		"node": true,
-		"es6": true
-	},
-	"parserOptions": {
-		"ecmaVersion": 2021
-	},
-	"rules": {
+```javascript
+const js = require('@eslint/js');
+
+module.exports = [
+	js.configs.recommended,
+	{
+		languageOptions: {
+			ecmaVersion: 'latest',
+		},
+		rules: {
 
-	}
-}
+		},
+	},
+];
 ```
 
 This is the basis of how an ESLint file will look. The `rules` object is where you'll define what rules you want to apply to ESLint. For example, if you want to make sure you never miss a semicolon, the `"semi": ["error", "always"]` rule is what you'll want to add inside that object.
 
 You can find a list of all of ESLint's rules on [their website](https://eslint.org/docs/rules). There are indeed many rules, and it may be overwhelming at first, so if you don't want to go through everything on your own yet, you can use these rules:
 
-```json {11-47}
