+#            === FLASHING WITH STOCK BOOTLOADER ===
+# You should make firmware for STM32F103 with bootloader offset
+# at 0x8008800 (Chitu v6 Bootloader) and serial (on USART1 PA10/PA9)
+# communication.
+
+# Use "./scripts/update_chitu.py ./out/klipper.bin ./out/update.cbd"
+# after make to generate update.cbd.  Put "update.cbd" file onto SD card,
+# and reboot the printer.
+# It will be automatically installed after you hear 2 beeps,
+# and you will be able to update it this way.
+
+# See docs/Config_Reference.md for a description of parameters.
