 ## 📜 About
 
-**eslint-config-conventions** is a [ESLint](https://eslint.org) configuration to enforce strict conventions and good code quality, it is highly inspired from [eslint-config-standard-with-typescript](https://github.com/standard/eslint-config-standard-with-typescript) but it is **stricter** and with **no formatting rules**, **only code-quality rules**. It supports both **JavaScript** and **TypeScript**.
+**eslint-config-conventions** is a [ESLint](https://eslint.org) configuration to enforce strict conventions and good code quality. It supports both **JavaScript** and **TypeScript**.
 
 This configuration is mostly **for catching bugs** and **code-quality** so it is recommended to use it with [Prettier](https://prettier.io/) for a consistent code style, it works with any `.prettierrc.json` configuration.

-### Configuration with [Prettier](https://prettier.io/) (recommended)
+### Configuration
 
-You will need to install some dependencies in addition to those required:
+#### `.eslintrc.json` (JavaScript)
+
+```json
+{
+  "root": true,
+  "extends": ["conventions"],
+  "plugins": ["promise", "unicorn"]
+}
+```

+      "parserOptions": {
+        "projectService": true
+      }
+    }
+  ]
+}
+```
+
+#### Configuration with [Prettier](https://prettier.io/) (recommended)
 
 ```sh
-npm install --save-dev prettier eslint-config-prettier eslint-plugin-prettier
+npm install --save-dev prettier
 
 # Create an empty config file to let editors and other tools know you are using Prettier
 # You can personalize it with your own rules
 echo "{}" > .prettierrc.json
 ```
 
-#### `.eslintrc.json`
+That's all! No need to update the `.eslintrc.json` configuration.
 
-```json
+We discourage usage of [eslint-config-prettier](https://github.com/prettier/eslint-config-prettier) and [eslint-plugin-prettier](https://github.com/prettier/eslint-plugin-prettier), as `eslint-config-conventions` doesn't include any stylistic rules, and including these packages has several drawbacks (listed in [Integrating with Linters](https://prettier.io/docs/en/integrating-with-linters.html)) and brings no benefits for this configuration.
