+### Notes on queueing failed messages
+When messages fail to be delivered they are queued for retry at 30 second interval with a maximum of 5 retries by default (can be configured)

+## Next steps
+
+### Security - HTTPS with client certificates
 HTTPS with client certificates should be implemented to ensure secure communication between servers and prevent unauthorized access and possible man-in-the-middle attacks.
+
+### Testing
+Full suite of unit tests should be implemented to ensure the correctness of the application's logic and behavior.
+
+### Finish implementation of Message Queue to queue failed messages for retry
