-Autonomous aerial surveillance drone with object tracking - AcreWatch project
+Autonomous aerial surveillance drone with object detection and tracking.
+Part of the AcreWatch project family.
+
+## What is this?
+
+Canopy is a custom-built drone platform that uses computer vision (YOLOv8) running on a Raspberry Pi 5 companion computer to detect and autonomously follow targets. Built on the ArduPilot flight stack with a Holybro X500 V2 frame.
