+# This file contains a configuration for the Anycubic Vyper printer from 2021.
+# It uses a clone of the STM32F103 chip named GD32F103.
+# There are 2 Mainboard versions out there v0.0.5 and v0.0.6, this config has
+# been tested with the v0.0.6 only. It should probably work for v0.0.5 as well
+# since there are no different changes in the Anycubic Marlin firmware.
+# The LCD is not supported yet (might work, but didn't try yet).
+#
+# To create the Firmware you need to use the following configuration:
+#     - Micro-controller: STM32
+#     - Processor model: STM32F103
+#     - Bootloader offset: 32KiB
+#     - Communication interface: Serial (on USART1 PA10/PA9)
+#
+# To install the Firmware rename the klipper bin to `main_board_20xxxxxx.bin`
+# and copy it to an SD Card.
+# Power off the Printer, insert the SD Card and power it on.
+# It should beep several times and the LCD should be stuck on the Splash screen.
+# Now you should be able to connect to the Printer, you might need to change
+# the mcu/serial setting in this config according to your set up.
+#
+# If you want to revert the Firmware back to Marlin you simply need to flash it
+# with a anycubic firmware through the SD Card
