+# Status update – September 2025
+
+Over the past year, my focus has shifted to other projects, and I’ve decided it’s time to close the chapter on this one. I will no longer provide updates or support, and the repository will be archived.
+
+This project has been a fun journey, and I’d like to thank everyone who used, contributed, or shared feedback along the way. Your interest and support kept it alive far longer than I originally expected.
+
+If you’re looking for a great alternative, I recommend [CA2RXU LoRa APRS Tracker/Station](https://github.com/richonguzman/LoRa_APRS_Tracker).

+#### Step on console
+
+You may not need to use PlatformIO because compilation and configuration can be done via console.
