+# `react-dom`
+
+This package serves as the entry point of the DOM-related rendering paths. It is intended to be paired with the isomorphic React, which will be shipped as `react` to npm.
+
+## Installation
+
+```sh
+npm install react react-dom
+```
+
+## Usage
+
+### In the browser
+
+```js
+var React = require('react');
+var ReactDOM = require('react-dom');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOM.render(<MyComponent />, node);
+```
+
+### On the server
+
+```js
+var React = require('react');
+var ReactDOMServer = require('react-dom/server');
+
+class MyComponent extends React.Component {
+  render() {
+    return <div>Hello World</div>;
+  }
+}
+
+ReactDOMServer.renderToString(<MyComponent />);
+```
+
+## API
+
+### `react-dom`
+
+- `findDOMNode`
+- `render`
+- `unmountComponentAtNode`
+
+### `react-dom/server`
+
+- `renderToString`
+- `renderToStaticMarkup`

+# react
+
+An npm package to get you immediate access to [React](https://facebook.github.io/react/),
+without also requiring the JSX transformer. This is especially useful for cases where you
+want to [`browserify`](https://github.com/substack/node-browserify) your module using
+`React`.
+
+**Note:** by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages.
+
+To use React in production mode, set the environment variable `NODE_ENV` to `production`. A minifier that performs dead-code elimination such as [UglifyJS](https://github.com/mishoo/UglifyJS2) is recommended to completely remove the extra code present in development mode.
+
+## Example Usage
+
+```js
+var React = require('react');
+
+// Addons are in separate packages:
+var createFragment = require('react-addons-create-fragment');
+var immutabilityHelpers = require('react-addons-update');
+var CSSTransitionGroup = require('react-addons-css-transition-group');
+```
+
+For a complete list of addons visit the [addons documentation page](https://facebook.github.io/react/docs/addons.html).
