+### Release Process
+
+Releases published on GitHub are **not immediately deployed to all devices in the market**. Each release first goes through internal testing, including limited deployments in select locations to verify stability and functionality.
+
+If the tests pass, the firmware is then made available for:
+- **FOTA (Firmware Over-The-Air) updates** from AirGradient dashboard
+- **Manual flashing** via [Airgradient](https://www.airgradient.com/documentation/firmwares/) website
+
+Each GitHub release note will also include the planned rollout date for wider availability.
