 <h1>Network Communications</h1>
 
 
 <p>
 Packaged apps can act as a network client
 for TCP and UDP connections.
 This doc shows you how to use TCP and UDP
 to send and receive data over the network.

 Packaged apps can make connections to any service that supports TCP.

-<h3>Connecting to a socket</h3>
+<h3 id="connecting">Connecting to a socket</h3>
 
 <p>
 Here's a sample showing how to connect to a socket:
 </p>
 
 <pre>
 chrome.socket.create('tcp', {}, function(createInfo) {
   socket.connect(createInfo.socketId, IP, PORT, onConnectedCallback);
 });
 </pre>
 
 <p>
 Keep a handle to the socketId so that
 you can later read and write to this socket.
 </p>
 
 <pre>
 chrome.socket.write(socketId, arrayBuffer, onWriteCompleteCallback);
 </pre>
 
-<h3>Reading to and writing from a socket</h3>
+<h3 id="reading">Reading to & writing from a socket</h3>
 
 <p>
 Reading and writing from a socket uses ArrayBuffer objects.
 </p>
 
 <pre>
 chrome.socket.read(socketId, null, function(readInfo) {
   if (readInfo.resultCode > 0) {
     // readInfo.data is an arrayBuffer.
   }
 });
 </pre>
 
-<h3>Disconnecting from a socket</h3>
+<h3 id="disconnecting">Disconnecting from a socket</h3>
 
 <p>Here's how to disconnect:</p>
 
 <pre>chrome.socket.disconnect(socketId);</pre>
 
 <h2 id="udp">Using UDP</h2>
 
 <p>
 Packaged apps can make connections to any service that supports UDP.
 </p>
 
-<h3>Sending data</h3>
+<h3 id="sending">Sending data</h3>
 
 <p>
 Here's a sample showing how to send data
 over the network using UDP:
 </p>
 
 <pre>
 // Create the Socket
 chrome.experimental.socket.create('udp', '127.0.0.1', 1337, {},
  function(socketInfo) {
    // The socket is created, now we want to connect to the service
    var socketId = socketInfo.socketId;
    chrome.experimental.socket.connect(socketId, function(result) {
      // We are now connected to the socket so send it some data
      chrome.experimental.socket.write(socketId, arrayBuffer,
        function(sendInfo) {
          console.log("wrote " + sendInfo.bytesWritten);
        }
      );
    });
  }
 );
 </pre>
 
-<h3>Receiving data</h3>
+<h3 id="receiving">Receiving data</h3>
 
 <p>
 This example is very similar to the 'Sending data' example
 with the addition of a special handler in the 'create' method.
 The parameter is an object with one value 'onEvent'
 that is a function reference to the method
 that will be called when data is available on the port.
