 #### Read the wiki [article](https://0xproject.com/wiki#0x-OrderWatcher).
 
+OrderWatcher also comes with a WebSocket server to provide language-agnostic access
+to order watching functionality. We used the [WebSocket Client and Server Implementation for Node](https://www.npmjs.com/package/websocket). The server sends and receives messages that conform to the [JSON RPC specifications](https://www.jsonrpc.org/specification).
+
 ## Installation

 }
 ```
 
+## Using the WebSocket Server
+
+**Setup**
+
+**Environmental Variables**
+Several environmental variables can be set to configure the server:
+
+*   `ORDER_WATCHER_HTTP_PORT` specifies the port that the http server will listen on
+    and accept connections from. When this is not set, we default to 8080.
+
+**Requests**
+The server accepts three types of requests: `ADD_ORDER`, `REMOVE_ORDER` and `GET_STATS`. These mirror what the underlying OrderWatcher does. You can read more in the [wiki](https://0xproject.com/wiki#0x-OrderWatcher). Unlike the OrderWatcher, it does not expose any `subscribe` or `unsubscribe` functionality because the WebSocket server keeps a single subscription open for all clients.
+
+The first step for making a request is establishing a connection with the server. In Javascript:
+
+```
+var W3CWebSocket = require('websocket').w3cwebsocket;
+wsClient = new W3CWebSocket('ws://127.0.0.1:8080');
+```
+
+In Python, you could use the [websocket-client library](http://pypi.python.org/pypi/websocket-client/) and run:
+
+```
+from websocket import create_connection
+wsClient = create_connection("ws://127.0.0.1:8080")
+```
+
+With the connection established, you prepare the payload for your request. The payload is a json object with a format established by the [JSON RPC specification](https://www.jsonrpc.org/specification):
+
+*   `id`: All requests require you to specify a numerical `id`. When the server responds to the request, the response will have the same `id` as the one supplied with your request.
+*   `jsonrpc`: This is always the string `'2.0'`.
+*   `method`: This specifies the OrderWatcher method you want to call. I.e., `'ADD_ORDER'`, `'REMOVE_ORDER'` or `'GET_STATS'`.
+*   `params`: These contain the parameters needed by OrderWatcher to execute the method you called. For `ADD_ORDER`, provide `{ signedOrder: <your signedOrder> }`. For `REMOVE_ORDER`, provide `{ orderHash: <your orderHash> }`. For `GET_STATS`, no parameters are needed, so you may leave this empty.
+
+Next, convert the payload to a string and send it through the connection.
+In Javascript:
+
+```
+const addOrderPayload = {
+    id: 1,
+    jsonrpc: '2.0',
+    method: 'ADD_ORDER',
+    params: { signedOrder: <your signedOrder> },
+};
+wsClient.send(JSON.stringify(addOrderPayload));
+```
+
+In Python:
+
+```
+import json
+remove_order_payload = {
+    'id': 1,
+    'jsonrpc': '2.0',
+    'method': 'REMOVE_ORDER',
+    'params': {'orderHash': '0x6edc16bf37fde79f5012088c33784c730e2f103d9ab1caf73060c386ad107b7e'},
+}
+wsClient.send(json.dumps(remove_order_payload));
+```
+
+**Response**
+The server responds to all requests in a similar format. In the data field, you'll find another object containing the following fields:
+
+*   `id`: The id corresponding to the request that the server is responding to. `UPDATE` responses are not based on any requests so the `id` field is omitted`.
+*   `jsonrpc`: Always `'2.0'`.
+*   `method`: The method the server is responding to. Eg. `ADD_ORDER`. When order states change the server may also initiate a response. In this case, method will be listed as `UPDATE`.
+*   `result`: This field varies based on the method. `UPDATE` responses contain the new order state. `GET_STATS` responses contain the current order count. When there are errors, this field is omitted.
+*   `error`: When there is an error executing a request, the [JSON RPC](https://www.jsonrpc.org/specification) error object is listed here. When the server responds successfully, this field is omitted.
+
+In Javascript, the responses can be parsed using the `onmessage` callback:
+
+```
+wsClient.onmessage = (msg) => {
+    const responseData = JSON.parse(msg.data);
+    const method = responseData.method
+};
+```
+
+In Python, `recv` is a lightweight way to receive a response:
+
+```
+result = wsClient.recv()
+method = result.method
+```
+
