 ## Introduction
 
 [*WebSocket*](https://en.wikipedia.org/wiki/WebSocket) is a computer communications protocol, providing full-duplex
-communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket communication, and for client HTTP communication. The code is derived from [easywsclient](https://github.com/dhbaird/easywsclient) and from the [Satori C SDK](https://github.com/satori-com/satori-rtm-sdk-c). It has been tested on the following platforms.

 ## Build
 
 CMakefiles for the library and the examples are available. This library has few dependencies, so it is possible to just add the source files into your project.
@@ -196,19 +134,25 @@ No manual polling to fetch data is required. Data is sent and received instantly
 
 If the remote end (server) breaks the connection, the code will try to perpetually reconnect, by using an exponential backoff strategy, capped at one retry every 10 seconds.
 
-### Large messages
-
-Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket [fragmentation](https://tools.ietf.org/html/rfc6455#section-5.4). Messages up to 500M were sent and received succesfully.
-
 ## Limitations
 
 * There is no text support for sending data, only the binary protocol is supported. Sending json or text over the binary protocol works well.
 * Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
-* The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.

+## Examples
+
+1. Bring up a terminal and jump to the examples folder.
+2. Compile the example C++ code. `sh build.sh`
+3. Install node.js from [here](https://nodejs.org/en/download/).
+4. Type `npm install` to install the node.js dependencies. Then `node broadcast-server.js` to run the server.
+5. Bring up a second terminal. `./cmd_websocket_chat bob`
+6. Bring up a third terminal. `./cmd_websocket_chat bill`
+7. Start typing things in any of those terminals. Hopefully you should see your message being received on the other end.
