+## Extracting Kernel from Built Image
+
+After the build completes, extract the kernel and related files:
+
+```bash
+# Your built image
+IMAGE="output/images/Armbian_*.img"
+
+# Mount the image locally using loop device
+sudo losetup -P /dev/loop0 $IMAGE
+sudo mkdir -p /mnt/armbian
+sudo mount /dev/loop0p1 /mnt/armbian
+
+# Backup kernel and boot files to current directory
+sudo tar czf armbian-kernel.tar.gz -C /mnt/armbian \
+  boot/ \
+  lib/modules/ \
+  lib/firmware/
+
+# Unmount
+sudo umount /mnt/armbian
+sudo losetup -d /dev/loop0
+```
+
 ## Notes
 
 - The kernel build uses Armbian's build system to generate a compatible kernel for the Odroid C4
