+## Future Usage
+
+**Note:** This package is not intended for public use at this time. The following is an example of how it will be used in the future.
+
+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";
+
+const compat = new FlatCompat();
+
+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: {
