+## Testing with WebSocat
+[WebSocat](https://github.com/vi/websocat) is a versatile tool for working with websockets from the command line. Below are some examples of using WebSocat to test the websocket endpoint:
+
+```bash
+# Start server
+make run
+``` 
+
+```bash
+# Connect to the websocket endpoint
+$ websocat ws://localhost:PORT/websocket
+```
+
+Replace `PORT` with the port number on which your server is running.
+
+## Sample Output
+Upon successful connection, the client should start receiving timestamp messages from the server every 2 seconds.
+
+```bash
+server timestamp: 1709046650354893857
+server timestamp: 1709046652355956336
