 ## Usage
 
+### Flat Config: eslint.config.js
+
+**Important:** Requires ESLint >=8.56.0 and eslint-config-ssjs >=2.0.0
+
+This plugin exports a recommended config that enforces good practices.
+
+#### ES Module (Recommended)
+
+The folowing will limit SSJS rules to files ending on `*.ssjs`:
+
+```js
+import sfmcSsjs from 'eslint-config-ssjs';
+
+export default [
+ // …
+ {
+ ...sfmcSsjs.configs.recommended,
+ files: ['**/*.ssjs'],
+ },
+];
+```
+
+If you don't plan on writing any browser (normal) JavaScript, you can also use the following. This will apply the rules to all files:ggn
+
+```js
+import sfmcSsjs from 'eslint-config-ssjs';
+
+export default [
+ // …
+ sfmcSsjs.configs.recommended,
+];
+```
+
+#### CommonJS
+
+```js
+'use strict';
+const sfmcSsjs = require('eslint-config-ssjs');
+
+module.exports = [
+ // …
+ {
+ ...sfmcSsjs.configs.recommended,
+ files: ['**/*.ssjs'],
+ },
+];
+```
+
+### Legacy: .eslintrc.\* or package.json
+
+**Important:** Requires ESLint <9.0.0 and eslint-config-ssjs <2.0.0
+
 Once the `eslint-config-ssjs` package is installed, you can use it by specifying `ssjs` in the [`extends`](http://eslint.org/docs/user-guide/configuring#extending-configuration-files) section of your [ESLint configuration](http://eslint.org/docs/user-guide/configuring).
 
 **Important:** Make sure that your SSJS files end on `*.ssjs` and not on `*.js`.
