+# ESLint JavaScript Plugin
+
+[Website](https://eslint.org) | [Configure ESLint](https://eslint.org/docs/latest/use/configure) | [Rules](https://eslint.org/docs/rules/) | [Contributing](https://eslint.org/docs/latest/contribute) | [Twitter](https://twitter.com/geteslint) | [Chatroom](https://eslint.org/chat)
+
+The beginnings of separating out JavaScript-specific functionality from ESLint.
+
+Right now, this plugin contains two configurations:
+
+* `recommended` - enables the rules recommended by the ESLint team (the replacement for `"eslint:recommended"`)
+* `all` - enables all ESLint rules (the replacement for `"eslint:all"`)
+
+## Installation
+
+```shell
+npm install @eslint/js -D
+```
+
+## Usage
+
+Use in your `eslint.config.js` file anytime you want to extend one of the configs:
+
+```js
+import js from "@eslint/js";
+
+export default [
+
+    // apply recommended rules to JS files
+    {
+        files: ["**/*.js"],
+        rules: js.configs.recommended.rules
+    },
+
+    // apply recommended rules to JS files with an override
+    {
+        files: ["**/*.js"],
+        rules: {
+            ...js.configs.recommended.rules,
+            "no-unused-vars": "warn"
+        } 
+    },
+
+    // apply all rules to JS files
+    {
+        files: ["**/*.js"],
+        rules: {
+            ...js.configs.all.rules,
+            "no-unused-vars": "warn"
+        } 
+    }
+]
+```
