+### Initial Flash
+
+For first Flashing from initial Stock's Firmware
+
+1. Back up original Firmware Image:
+- Unplug
+- Short Boot0 to Vdd (See below)
+- Plug In USB
+- Make a Flash Image's Backup in case you wanted to restore the Keyboard to Stock's Image:
+  - Using DFUseDemo.exe from ST's STSW-STM32080: https://www.st.com/en/development-tools/stsw-stm32080.html
+  - Using dfu-util (thanks to [tylert](https://github.com/tylert) for instructions!):
+
+
+    dfu-util --list
+    dfu-util --alt 0 --dfuse-address 0x08000000 --upload ${OLD_STOCK_BIN}
+
+2. Flash the QMK Firmware Image.
+- Put board into Bootloader mode, using the same method as when backing up the original Firmware (above)
+- Here are a few options for performing the initial Flash:
+  - Using [QMK Toolbox](https://github.com/qmk/qmk_toolbox)
+  - Using DFuseDemo.exe if STTub30 driver is used.
+  - Using dfu-util:
+
+
+    dfu-util --alt 0 --dfuse-address 0x08000000 --upload ${NEW_QMK_BIN}
+
+You can short Boot0 to Vdd by shorting R21 to C27 on the sides closest to the processor, as shown:
