+# `react-dom`
+
+This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as `react` to npm.
+
+## Installation
+
+```sh
+npm install react react-dom
+```
+
+## Usage
+
+### In the browser
+
+```js
+import { createRoot } from 'react-dom/client';
+
+function App() {
+  return <div>Hello World</div>;
+}
+
+const root = createRoot(document.getElementById('root'));
+root.render(<App />);
+```
+
+### On the server
+
+```js
+import { renderToPipeableStream } from 'react-dom/server';
+
+function App() {
+  return <div>Hello World</div>;
+}
+
+function handleRequest(res) {
+  // ... in your server handler ...
+  const stream = renderToPipeableStream(<App />, {
+    onShellReady() {
+      res.statusCode = 200;
+      res.setHeader('Content-type', 'text/html');
+      stream.pipe(res);
+    },
+    // ...
+  });
+}
+```
