 You can generate a demo AsyncAPI specification using the `server-demo` package. A pregenerated specification already exists in the `specs` directory. If you want to generate the specification again, you can use the following command, where `main.bal` is the Ballerina file that contains the entry point to the WebSocket service.
 
 ```bash
+cd server-demo
 bal asyncapi --protocol ws -i main.bal -o specs
 ```
 
 ## A client-server example
 
-The `client` package and the `server` package are a simple example of a client-server application. The client sends a message to the server, which responds with a message, and the client logs the response. The client continuously listens for messages from the server. 
+The `client` and `server` packages exemplify a basic client-server application. The client sends a message to the server, which responds with a message, and the client logs the response. The client continuously listens for messages from the server.
 
 You can have two instances of the client to pass messages between them through the server.
 
 In the `client` package, the files `client.bal`, `types.bal`, and `utils.bal` are generated by the AsyncAPI tool, whereas the `main.bal` file is an example usage of the generated client.
 
-In the `server` package, the `messages.md` file contains the message examples that the server expects. The `main.bal` file is the WebSocket server implementation.
+In the `server` package, the `messages.md` file provides example messages outlining the expected structure by the server. The `main.bal` file contains the WebSocket server implementation.
 
 You can regenerate the client using the following command:
 
 ```bash
+cd client
 bal asyncapi --protocol ws -i asyncapi.yaml
 ```
