 ## Features
 This library supports all of the features the JS client does, including events, options and upgrading transport. Android is fully supported.
 
-### Extra features only for Java client
-
-#### Accessing HTTP Headers
-You can access HTTP headers like the following.
-
-```java
-socket.on(Socket.EVENT_TRANSPORT, new Emitter.listener() {
-  @Override
-  public void call(Object... args) {
-    // Called on a new transport created.
-    Transport transport = (Transport)args[0];
-
-    transport.on(Transport.EVENT_REQUEST_HEADERS, new Emitter.Listener() {
-      @Override
-      public void call(Object... args) {
-        @SuppressWarnings("unchecked")
-        Map<String, List<String>> headers = (Map<String, List<String>>)args[0];
-        // send cookie value to server.
-        headers.put("Cookie", Arrays.asList("foo=1;"));
-      }
-    }).on(Transport.EVENT_RESPONSE_HEADERS, new Emitter.Listener() {
-      @Override
-      public void call(Object... args) {
-        @SuppressWarnings("unchecked")
-        Map<String, List<String>> headers = (Map<String, List<String>>)args[0];
-        // receive cookie value from server.
-        String cookie = headers.get("Set-Cookie").get(0);
-      }
-    });
-  }
-});
-```

+### Maven
+Add the following dependency to your `pom.xml`.
+
+```xml
+<dependencies>
+  <dependency>
+    <groupId>io.socket</groupId>
+    <artifactId>engine.io-client</artifactId>
+    <version>1.0.1</version>
+  </dependency>
+</dependencies>
+```
+
+### Gradle
+Add it as a gradle dependency for Android Studio, in `build.gradle`:
+
+```groovy
+compile ('io.socket:engine.io-client:1.0.1') {
+  // excluding org.json which is provided by Android
+  exclude group: 'org.json', module: 'json'
+}
+```

+## Usage
+Engine.IO-client Java has the similar api with the JS client. You can use `Socket` to connect:
+
+```java
+socket = new Socket("ws://localhost");
+socket.on(Socket.EVENT_OPEN, new Emitter.Listener() {
+  @Override
+  public void call(Object... args) {
+    socket.send("hi");
+    socket.close();
+  }
+});
+socket.open();
+```
+
+You can listen events as follows:
+
+```java
+socket.on(Socket.EVENT_MESSAGE, new Emitter.Listener() {
+  @Override
+  public void call(Object... args) {
+    String data = (String)args[0];
+  }
+}).on(Socket.EVENT_ERROR, new Emitter.Listener() {
+  @Override
+  public void call(Object... args) {
+    Exception err = (Exception)args[0];
+  }
+});
+```
+
+How to set options:
+
+```java
+opts = new Socket.Options();
+opts.transports = new String[] {WebSocket.NAME};
+
+socket = new Socket(opts);
+```
+
+Sending and receiving binary data:
+
+```java
+socket = new Socket();
+socket.on(Socket.EVENT_OPEN, new Emitter.Listener() {
+  @Override
+  public void call(Object... args) {
+    // send binary data
+    byte[] data = new byte[42];
+    socket.send(data);
+  }
+}).on(Socket.EVENT_MESSAGE, new Emitter.Listener() {
+  @Override
+  public void call(Object... args) {
+    // receive binary data
+    byte[] data = (byte[])args[0];
+  }
+});
+```
+
+Use custom SSL settings:
+
+```java
+OkHttpClient okHttpClient = new OkHttpClient.Builder()
+    .hostnameVerifier(myHostnameVerifier)
+    .sslSocketFactory(mySSLContext.getSocketFactory(), myX509TrustManager)
+    .build();
+
+// default SSLContext for all sockets
+Socket.setDefaultOkHttpWebSocketFactory(okHttpClient);
+Socket.setDefaultOkHttpCallFactory(okHttpClient);
+
+// set as an option
+opts = new Socket.Options();
+opts.callFactory = okHttpClient;
+opts.webSocketFactory = okHttpClient;
+socket = new Socket(opts);
+```
