+# ESLintRC Library
+
+This repository contains the legacy ESLintRC configuration file format for ESLint. This package is not intended for use outside of the ESLint ecosystem. It is ESLint-specific and not intended for use in other programs.
+
+**Note:** This package is frozen except for critical bug fixes as ESLint moves to a new config system.
+
+## Installation
+
+You can install the package as follows:
+
+```
+npm install @eslint/eslintrc --save-dev
+
+# or
+
+yarn add @eslint/eslintrc -D
+```
+
+## Usage (ESM)
+
+The primary class in this package is `FlatCompat`, which is a utility to translate ESLintRC-style configs into flat configs. Here's how you use it inside of your `eslint.config.js` file:
+
+```js
+import { FlatCompat } from "@eslint/eslintrc";
+import js from "@eslint/js";
+import path from "path";
+import { fileURLToPath } from "url";
+
+// mimic CommonJS variables -- not needed if using CommonJS
+const __filename = fileURLToPath(import.meta.url);
+const __dirname = path.dirname(__filename);
+
+const compat = new FlatCompat({
+    baseDirectory: __dirname,                  // optional; default: process.cwd()
+    resolvePluginsRelativeTo: __dirname,       // optional
+    recommendedConfig: js.configs.recommended, // optional
+    allConfig: js.configs.all,                 // optional
+});
+
+export default [
+
+    // mimic ESLintRC-style extends
+    ...compat.extends("standard", "example"),
+
+    // mimic environments
+    ...compat.env({
+        es2020: true,
+        node: true
+    }),
+
+    // mimic plugins
+    ...compat.plugins("airbnb", "react"),
+
+    // translate an entire config
+    ...compat.config({
+        plugins: ["airbnb", "react"],
+        extends: "standard",
+        env: {
+            es2020: true,
+            node: true
+        },
+        rules: {
+            semi: "error"
+        }
+    })
+];
+```
+
+## Usage (CommonJS)
+
+Using `FlatCompat` in CommonJS files is similar to ESM, but you'll use `require()` and `module.exports` instead of `import` and `export`. Here's how you use it inside of your `eslint.config.js` CommonJS file:
+
+```js
+const { FlatCompat } = require("@eslint/eslintrc");
+const js = require("@eslint/js");
+
+const compat = new FlatCompat({
+    baseDirectory: __dirname,                  // optional; default: process.cwd()
+    resolvePluginsRelativeTo: __dirname,       // optional
+    recommendedConfig: js.configs.recommended, // optional
+    allConfig: js.configs.all,                 // optional
+});
+
+module.exports = [
+
+    // mimic ESLintRC-style extends
+    ...compat.extends("standard", "example"),
+
+    // mimic environments
+    ...compat.env({
+        es2020: true,
+        node: true
+    }),
+
+    // mimic plugins
+    ...compat.plugins("airbnb", "react"),
+
+    // translate an entire config
+    ...compat.config({
+        plugins: ["airbnb", "react"],
+        extends: "standard",
+        env: {
+            es2020: true,
+            node: true
+        },
+        rules: {
+            semi: "error"
+        }
+    })
+];
+```

+/**
+ * @fileoverview `ConfigArray` class.
+ *
+ * `ConfigArray` class expresses the full of a configuration. It has the entry
+ * config file, base config files that were extended, loaded parsers, and loaded
+ * plugins.
+ *
+ * `ConfigArray` class provides three properties and two methods.
+ *
+ * - `pluginEnvironments`
+ * - `pluginProcessors`
+ * - `pluginRules`
+ *      The `Map` objects that contain the members of all plugins that this
+ *      config array contains. Those map objects don't have mutation methods.
+ *      Those keys are the member ID such as `pluginId/memberName`.
+ * - `isRoot()`
+ *      If `true` then this configuration has `root:true` property.
+ * - `extractConfig(filePath)`
+ *      Extract the final configuration for a given file. This means merging
+ *      every config array element which that `criteria` property matched. The
+ *      `filePath` argument must be an absolute path.
+ *
+ * `ConfigArrayFactory` provides the loading logic of config files.

+# 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"
+        }
