+### Malyan M200 Build Instructions
+
+Malyan M200 series firmware currently builds using the Arduino IDE. These instructions should 
+guide you through the configuration and compilation.
+
+1. Install the Arduino IDE from your favorite source (arduino.cc, windows store, app store)
+2. Launch the IDE to add the ST boards manager:
+   - Open the **Preferences** dialog.
+   - Add this link in the "*Additional Boards Managers URLs*" field:
+      https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json
+   - Select "**Show verbose ouptut during: compilation**."
+3. Select **Tools** > **Board** > **Boards Manager**.
+4. Type "Malyan" into the Search field.
+5. The only board listed will be "**STM32 Cores by STMicroelectronics**." Any version from 1.6.0 up is fine. Choose install. This will download many tools and packages, be patient.
+6. Open the **Tools** > **Board** submenu, scroll all the way down, and select **3D Printer Boards**.
+7. From the **Tools** menu, select a board part number:
+   - If you own a M200 V1 or early run (black V2), choose **Malyan M200 V1**.
+   - If you own a M200 V2 later run (white/black) or V3 (Pro), choose **Malyan M200 V2** (The V2 and V3 both share an STM32F070 MCU). Note that the V3 pinout is not complete (autolevel doesn't work as of this writing).
+8. From the **Tools** menu, choose **USB Support** > **CDC No Generic Serial**.
+9. Download the latest Marlin source (from the [bugfix-2.0.x](https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.0.x) branch) and unzip it.
+10. Look in the `Marlin` subdirectory for the `Configuration.h` and `Configuration_adv.h` files. Replace these files with the configurations in the `config\examples\Malyan\M200` folder.
+11. If you have an early-run V2, the steps-per-mm are roughly half. Consult the [mpminipro.com wiki](https://mpminipro.com/) for the steps that apply to your unit. Modify `Configuration.h`.
+12. Inverting Axis. There's no pattern to axes will need to be inverted. The only way to know is to test your particular printer. If you *do* know, go ahead and invert the correct axes.
+13. Open the `Marlin/Marlin.ino` file in Arduino IDE.
+14. From the **Sketch** menu, select **File** > **Export Compiled Binary**.
+15. When compilation is done you've built the firmware. The next stage is to flash it to the board. To do this look for a line like this: `"path/to/bin/arm-none-eabi-objcopy" -O binary "/path/to/Marlin.ino.elf" "/path/to/Marlin.ino.bin"`
+  The file `Marlin.ino.bin` is your firmware binary. M200 (v1-3) and M300 printers require flashing via SD card. Use the SD card that came with the printer if possible. The bootloader is very picky about SD cards. Copy `Marlin.ino.bin` to your SD card under three names: `firmware.bin`, `update.bin`, and `fcupdate.flg`.
+16. Insert the SD card into your printer. Make sure the X and Y axes are centered in the middle of the bed. (When X and Y endstops are closed this signals a UI upgrade to the bootloader.)
+17. Power-cycle the printer. The first flash may take longer. Don't be surprised if the .99 version number doesn't show up until after the UI has launched the default screen.
+18. Remove the SD card and delete the `fcupdate.flg` file from the card to prevent an accidental re-flash. 
+19. Test the endstops and homing directions, run M303 PID autotune, and verify all features are working correctly.
+
+Welcome to Marlin 2.x...
