-### BREAKING CHANGES
-
-* the Socket#use() method is removed (see [5c73733](https://github.com/socketio/socket.io/commit/5c737339858d59eab4b5ee2dd6feff0e82c4fe5a))
-
-* Socket#join() and Socket#leave() do not accept a callback argument anymore.
-
-Before:
-
-```js
-socket.join("room1", () => {
- io.to("room1").emit("hello");
-});
-```
-
-After:
-
-```js
-socket.join("room1");
-io.to("room1").emit("hello");
-// or await socket.join("room1"); for custom adapters
-```
-
-* the "connected" map is renamed to "sockets"
-* the Socket#binary() method is removed, as this use case is now covered by the ability to provide your own parser.
-* the 'origins' option is removed
-
-Before:
-
-```js
-new Server(3000, {
-  origins: ["https://example.com"]
-});
-```
-
-The 'origins' option was used in the allowRequest method, in order to
-determine whether the request should pass or not. And the Engine.IO
-server would implicitly add the necessary Access-Control-Allow-xxx
-headers.
-
-After:
-
-```js
-new Server(3000, {
-  cors: {
-    origin: "https://example.com",
-    methods: ["GET", "POST"],
-    allowedHeaders: ["content-type"]
-  }
-});
-```
-
-The already existing 'allowRequest' option can be used for validation:
-
-```js
-new Server(3000, {
-  allowRequest: (req, callback) => {
-    callback(null, req.headers.referer.startsWith("https://example.com"));
-  }
-});
-```
-
-* Socket#rooms is now a Set instead of an object
-
-* Namespace#connected is now a Map instead of an object
-
-* there is no more implicit connection to the default namespace:
-
-```js
-// client-side
-const socket = io("/admin");
-
-// server-side
-io.on("connect", socket => {
-  // not triggered anymore
-})
-
-io.use((socket, next) => {
-  // not triggered anymore
-});
-
-io.of("/admin").use((socket, next) => {
-  // triggered
-});
-```
-
-* the Server#set() method was removed
-
-This method was kept for backward-compatibility with pre-1.0 versions.

-- a [Javascript client library](https://github.com/socketio/socket.io-client) for the browser (or a Node.js client)
-
-Some implementations in other languages are also available:
-
-- [Java](https://github.com/socketio/socket.io-client-java)
-- [C++](https://github.com/socketio/socket.io-client-cpp)
-- [Swift](https://github.com/socketio/socket.io-client-swift)
-- [Dart](https://github.com/rikulo/socket.io-client-dart)
-
-Its main features are:
-
-#### Reliability
-
-Connections are established even in the presence of:
-  - proxies and load balancers.
-  - personal firewall and antivirus software.
-
-For this purpose, it relies on [Engine.IO](https://github.com/socketio/engine.io), which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information.
-
-#### Auto-reconnection support
-
-Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://github.com/socketio/socket.io-client/blob/master/docs/API.md#new-managerurl-options).
-
-#### Disconnection detection
-
-A heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore.
-
-That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes.
-
-#### Binary support
-
-Any serializable data structures can be emitted, including:
-
-- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser
-- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js
-
-#### Simple and convenient API
-
-Sample code:
-
-```js
-io.on('connection', socket => {
-  socket.emit('request', /* … */); // emit an event to the socket
-  io.emit('broadcast', /* … */); // emit an event to all connected sockets
-  socket.on('reply', () => { /* … */ }); // listen to the event
-});
 ```
-
-#### Cross-browser
-
-Browser support is tested in Sauce Labs:
-
-[![Sauce Test Status](https://saucelabs.com/browser-matrix/socket.svg)](https://saucelabs.com/u/socket)
-
-#### Multiplexing support
-
-In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection.
-
-#### Room support
-
-Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.
-
-This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example.
-
-
-**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol).
-
-## Installation
-
-```bash
 npm install socket.io
 ```
 
 ## How to use
 
-The following example attaches socket.io to a plain Node.JS
-HTTP server listening on port `3000`.
+First, require `socket.io` and attach it to a HTTP/HTTPS server:
 
 ```js
-const server = require('http').createServer();
-const io = require('socket.io')(server);
-io.on('connection', client => {
-  client.on('event', data => { /* … */ });
-  client.on('disconnect', () => { /* … */ });
+var app = express.createServer()
+  , io = require('socket.io')(app);
+
+app.listen(80);
+
+io.on('connection', function (socket) {
+  socket.emit('news', { hello: 'world' });
+  socket.on('my other event', function (data) {
+    console.log(data);
+  });
 });
-server.listen(3000);
 ```
 
-### Standalone
+Finally, load it from the client side code:
+
+```html
+<script src="/socket.io/socket.io.js"></script>
+<script>
+  var socket = io.connect('http://localhost');
+  socket.on('news', function (data) {
+    console.log(data);
+    socket.emit('my other event', { my: 'data' });
+  });
+</script>
+```
+
+For more thorough examples, look at the `examples/` directory.
+
+## Short recipes
+
+### Sending and receiving events.
+
+Socket.IO allows you to emit and receive custom events.
+Besides `connect`, `message` and `disconnect`, you can emit custom events:
 
 ```js
-const io = require('socket.io')();
-io.on('connection', client => { ... });
-io.listen(3000);
+// note, io(<port>) will create a http server for you
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  io.emit('this', { will: 'be received by everyone' });
+
+  socket.on('private message', function (from, msg) {
+    console.log('I received a private message by ', from, ' saying ', msg);
+  });
+
+  socket.on('disconnect', function () {
+    io.emit('user disconnected');
+  });
+});
 ```
 
-### In conjunction with Express
+### Storing data associated to a client
 
-Starting with **3.0**, express applications have become request handler
-functions that you pass to `http` or `http` `Server` instances. You need
-to pass the `Server` to `socket.io`, and not the express application
-function. Also make sure to call `.listen` on the `server`, not the `app`.
+Sometimes it's necessary to store data associated with a client that's
+necessary for the duration of the session.
+
+#### Server side
 
 ```js
-const app = require('express')();
-const server = require('http').createServer(app);
-const io = require('socket.io')(server);
-io.on('connection', () => { /* … */ });
-server.listen(3000);
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.on('set nickname', function (name) {
+    socket.set('nickname', name, function () { socket.emit('ready'); });
+  });
+
+  socket.on('msg', function () {
+    socket.get('nickname', function (err, name) {
+      console.log('Chat message by ', name);
+    });
+  });
+});
 ```
 
-### In conjunction with Koa
+#### Client side
 
-Like Express.JS, Koa works by exposing an application as a request
-handler function, but only by calling the `callback` method.
+```html
+<script>
+  var socket = io.connect('http://localhost');
+
+  socket.on('connect', function () {
+    socket.emit('set nickname', confirm('What is your nickname?'));
+    socket.on('ready', function () {
+      console.log('Connected !');
+      socket.emit('msg', confirm('What is your message?'));
+    });
+  });
+</script>
+```
+
+#### Client side
+
+In the client side, messages are received the same way whether they're volatile
+or not.
+
+### Getting acknowledgements
+
+Sometimes, you might want to get a callback when the client confirmed the message
+reception.
+
+To do this, simply pass a function as the last parameter of `.emit`.
+What's more, when you use `.emit`, the acknowledgement is done by you, which
+means you can also pass data along:
+
+#### Server side
 
 ```js
-const app = require('koa')();
-const server = require('http').createServer(app.callback());
-const io = require('socket.io')(server);
-io.on('connection', () => { /* … */ });
-server.listen(3000);
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.on('ferret', function (name, fn) {
+    fn('woot');
+  });
+});
 ```
 
-### In conjunction with Fastify
+#### Client side
 
-To integrate Socket.io in your Fastify application you just need to
-register `fastify-socket.io` plugin. It will create a `decorator`
-called `io`.
+```html
+<script>
+  var socket = io.connect(); // TIP: .connect with no args does auto-discovery
+  socket.on('connect', function () { // TIP: you can avoid listening on `connect` and listen on events directly too!
+    socket.emit('ferret', 'tobi', function (data) {
+      console.log(data); // data will be 'woot'
+    });
+  });
+</script>
+```
+
+### Broadcasting messages
+
+To broadcast, simply add a `broadcast` flag to `emit` and `send` method calls.
+Broadcasting means sending a message to everyone else except for the socket
+that starts it.
+
+#### Server side
 
 ```js
-const app = require('fastify')();
-app.register(require('fastify-socket.io'));
-app.io.on('connection', () => { /* … */ });
-app.listen(3000);
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.broadcast.emit('user connected');
+});
 ```
 
-## Documentation
+### Rooms
 
-Please see the documentation [here](https://socket.io/docs/).
+Sometimes you want to put certain sockets in the same room, so that it's easy
+to broadcast to all of them together.
 
-The source code of the website can be found [here](https://github.com/socketio/socket.io-website). Contributions are welcome!
+Think of this as built-in channels for sockets. Sockets `join` and `leave`
+rooms in each socket.
 
-## Debug / logging
+#### Server side
 
-Socket.IO is powered by [debug](https://github.com/visionmedia/debug).
-In order to see all the debug output, run your app with the environment variable
-`DEBUG` including the desired scope.
+```js
+var io = require('socket.io')(80);
 
-To see the output from all of Socket.IO's debugging scopes you can use:
-
-```
-DEBUG=socket.io* node myapp
+io.on('connection', function (socket) {
+  socket.join('justin bieber fans');
+  socket.broadcast.to('justin bieber fans').emit('new fan');
+  io.to('rammstein fans').emit('new non-fan');
+});
 ```
 
-## Testing
+### Using it just as a cross-browser WebSocket
 
+If you just want the WebSocket semantics, you can do that too.
+Simply leverage `send` and listen on the `message` event:
+
+#### Server side
+
+```js
+var io = require('socket.io')(80);
+
+io.on('connection', function (socket) {
+  socket.on('message', function () { });
+  socket.on('disconnect', function () { });
+});
 ```
-npm test
+
+#### Client side
+
+```html
+<script>
+  var socket = io.connect('http://localhost/');
+  socket.on('connect', function () {
+    socket.send('hi');
+
+    socket.on('message', function (msg) {
+      // my msg
+    });
+  });
+</script>
 ```
-This runs the `gulp` task `test`. By default the test will be run with the source code in `lib` directory.
 
-Set the environmental variable `TEST_VERSION` to `compat` to test the transpiled es5-compat version of the code.
+### Messaging between clients
 
-The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test.
+Each client joins its own group, identified by the client id, which means you
+can leverage `to` to message a particular client:
 
+```js
+var io = require('socket.io')(80);
+io.on('connection', function (socket) {
+  socket.on('salutate', function (id) {
+    io.to(id)
+      .emit('hi!')
+      .on('disconnect', function () {
+        socket.emit('friend disconnected');
+      });
+  });
+});
+```

-# Socket.IO Chat with haproxy & redis
-
-A simple chat demo for socket.io
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-This will start four Socket.IO nodes, behind a haproxy instance which will loadbalance the requests (using a cookie for sticky sessions, see [cookie](https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4.2-cookie)).
-
-Each node connects to the redis backend, which will enable to broadcast to every client, no matter which node it is currently connected to.
-
-```
-# you can kill a given node, the client should reconnect to another node
-$ docker-compose stop server-george
-```
-
-## Features
-
-- Multiple users can join a chat room by each entering a unique username
-on website load.
-- Users can type chat messages to the chat room.
-- A notification is sent to all users when a user joins or leaves
-the chatroom.

-# Socket.IO Chat with httpd & redis
-
-A simple chat demo for socket.io
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-This will start four Socket.IO nodes, behind a httpd proxy which will loadbalance the requests (using a cookie for sticky sessions, see [cookie](http://httpd.apache.org/docs/2.4/fr/mod/mod_proxy_balancer.html)).
-
-Each node connects to the redis backend, which will enable to broadcast to every client, no matter which node it is currently connected to.
-
-```
-# you can kill a given node, the client should reconnect to another node
-$ docker-compose stop server-george
-```
-
-## Features
-
-- Multiple users can join a chat room by each entering a unique username
-on website load.
-- Users can type chat messages to the chat room.
-- A notification is sent to all users when a user joins or leaves
-the chatroom.

-# Socket.IO Chat with nginx & redis
-
-A simple chat demo for socket.io
-
-## How to use
-
-Install [Docker Compose](https://docs.docker.com/compose/install/), then:
-
-```
-$ docker-compose up -d
-```
-
-And then point your browser to `http://localhost:3000`.
-
-This will start four Socket.IO nodes, behind a nginx proxy which will loadbalance the requests (using the IP of the client, see [ip_hash](http://nginx.org/en/docs/http/ngx_http_upstream_module.html#ip_hash)).
-
-Each node connects to the redis backend, which will enable to broadcast to every client, no matter which node it is currently connected to.
-
-```
-# you can kill a given node, the client should reconnect to another node
-$ docker-compose stop server-george
-```
-
-## Features
-
-- Multiple users can join a chat room by each entering a unique username
-on website load.
-- Users can type chat messages to the chat room.
-- A notification is sent to all users when a user joins or leaves
-the chatroom.

-This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
-
-## Available Scripts
-
-In the project directory, you can run:
-
-### `yarn start`
-
-Runs the app in the development mode.<br />
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
-
-The page will reload if you make edits.<br />
-You will also see any lint errors in the console.
-
-### `yarn start-server`
-
-Starts the Socket.IO server.
-
-### `yarn test`
-
-Launches the test runner in the interactive watch mode.<br />
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
-
-### `yarn build`
-
-Builds the app for production to the `build` folder.<br />
-It correctly bundles React in production mode and optimizes the build for the best performance.
-
-The build is minified and the filenames include the hashes.<br />
-Your app is ready to be deployed!
-
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
-
-### `yarn eject`
-
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
-
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
-
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
-
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
-
-## Learn More
-
-You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).

-# Socket.IO custom parsers
-
-Since Socket.IO version 2.0.0, you can provide your custom parser, according to the needs of your application.
-
-Several parsers are showcased here:
-
-- the default one: [socket.io-parser](https://github.com/socketio/socket.io-parser)
-- one based on msgpack: [socket.io-msgpack-parser](https://github.com/darrachequesne/socket.io-msgpack-parser)
-- one based on native JSON: [socket.io-json-parser](https://github.com/darrachequesne/socket.io-json-parser)
-- a custom one based on [schemapack](https://github.com/phretaddin/schemapack)
-
-They are tested with various payloads:
-
-- string: `['1', '2', ... '1000']`
-- numeric: `[1, 2, ... 1000]`
-- binary: `Buffer.allocUnsafe(1000), where buf[i] = i`
-
-## How to use
-
-```
-$ npm i && npm start
-```
-
-## Results
-
-| bytes / packet | CONNECT packet | string | numeric | binary    |
-|----------------|----------------|--------|---------|-----------|
-| default        | 1              | 5903   | 3904    | 43 + 1000 |
-| msgpack        | 20             | 3919   | 2646    | 1029      |
-| JSON           | 20             | 5930   | 3931    | 3625      |
-| schemapack     | 20             | 3895   | 2005    | 1005      |
-
-## Comparison
-
-`default parser`
-- supports any serializable datastructure, including Blob and File
-- **but** binary payload is encoded as 2 packets
-
-`msgpack`
-- the size of payloads containing mostly numeric values will be greatly reduced
-- **but** rely on [ArrayBuffer](https://caniuse.com/#feat=typedarrays) in the browser (IE > 9)
-
-`JSON`
-- optimized
-- **but** does not support binary payloads
-
-`schemapack`
-- the most efficient in both speed and size
-- **but** you have to provide a schema for each packet
