+## Conclusion
+
+This tutorial showed how to create an OpenThread Border Router using the Arduino Nano Matter and the Nano ESP32 alongside a Linux computer. With this solution you can easily integrate and control Matter Accessory Devices for Smart Homes or Industries.
+
+### Next Steps
+
+Now that you know how to create your own Thread Border Router you can continue developing a custom platform or application that uses the CHIP Tool API to control the Matter end-devices from a mobile app or web platform with user-friendly dashboards and interfaces.
