 ### Cypress and Chai recommended
 
-[eslint-plugin-chai-friendly](https://www.npmjs.com/package/eslint-plugin-chai-friendly) is combined with the Cypress plugin `eslint-plugin-cypress`.
+[eslint-plugin-chai-friendly](https://www.npmjs.com/package/eslint-plugin-chai-friendly) (minimum version [eslint-plugin-chai-friendly@0.8.0](https://github.com/ihordiachenko/eslint-plugin-chai-friendly/releases/tag/v0.8.0) required for ESLint v9 support and flat config support) is combined with the Cypress plugin `eslint-plugin-cypress`.
 
-The [eslint-plugin-chai-friendly@0.7.4](https://github.com/ihordiachenko/eslint-plugin-chai-friendly/releases/tag/v0.7.4) plugin is not directly compatible with ESLint `9.x` or with flat config. Utilities offered by ESLint enable this plugin to be used nevertheless:
-
-- [@eslint/compat](https://www.npmjs.com/package/@eslint/compat)
-- [@eslint/eslintrc](https://www.npmjs.com/package/@eslint/eslintrc) using the `FlatCompat` class
-
-The recommended rules for both plugins are used: `cypress/recommended` and `plugin:chai-friendly/recommended`.
+The recommended rules for both plugins are used: `pluginCypress.configs.recommended` and `pluginChaiFriendly.configs.recommended`:
 
 ```shell
-npm install @eslint/compat @eslint/eslintrc eslint-plugin-chai-friendly --save-dev
+npm install eslint-plugin-chai-friendly@^0.8.0 --save-dev
 ```
 
 ```js
-import { fixupConfigRules } from '@eslint/compat'
-import { FlatCompat } from '@eslint/eslintrc'
 import pluginCypress from 'eslint-plugin-cypress/flat'
