+# a "28KiB bootloader" and serial (on USART1 PA10/PA9) communication.
+
+# Flash this firmware by copying "out/klipper.bin" to a SD card and
+# If you prefer a direct serial connection, in "make menuconfig"
+# select "Enable extra low-level configuration options" and select
+# serial (on USART3 PB11/PB10), which is broken out on the 10 pin IDC
+# cable used for the LCD module as follows:
+# 3: Tx, 4: Rx, 9: GND, 10: VCC
+
+# turning on the printer with the card inserted. The firmware
+# filename must end in ".bin" and must not match the last filename
+# that was flashed.
