+SockJS Mode
+===============
+
+By using the `useSockJs` option like below, DDP connection will use [SockJs](https://github.com/sockjs) protocol to establish the WebSocket connection.
+
+```js
+var ddpClient = new DDPClient({ useSockJs: true });
+```
+
+Meteor server uses SockJs to implement it's DDP server. With this mode, we can get the benefits provided by [meteorhacks:cluster](https://github.com/meteorhacks/cluster). Some of those are load balancing and service discovery.
+
+* For load balancing you don't need to anything.
+* For service discovery, just use the `path` option to identify the service you are referring to.
+
+> With this mode, `path` option has a special meaning. So, thing twice before using `path` option when you are using this option.
+
 Unimplemented Features
 ====
 The node DDP client does not implement ordered collections, something that while in the DDP spec has not been implemented in Meteor yet.
