+TRUE PLUG-AND-PLAY BACKUP USB
+============================
+
+🚀 AUTOMATIC BACKUP:
+1. Boot from this USB
+2. Wait 5 seconds (automatic backup starts)
+3. Wait for 10-second countdown
+4. Backup runs automatically (15-20 minutes)
+5. System reboots when done
+
+🔧 MANUAL BACKUP:
+1. Boot from USB
+2. Select "Manual Backup Mode"
+3. Follow prompts to select drives
+4. Backup proceeds automatically
+
+💾 RESTORE SYSTEM:
+1. Boot from USB
+2. Select "Alpine Linux (Recovery Console)"
+3. Run: /restore_XXXXXXXX.sh /dev/target_drive
+4. Follow prompts
+
+TRULY AUTOMATIC:
+- No Clonezilla menus
+- No device selection
+- No compression choices
+- Just boot and wait!
