-YMD75 / MT84
-==========================
+# YMD75 / MT84
 
-This is a port of the QMK firmware for boards that are based on the
-ps2avrGB firmware, like the [ps2avrGB keyboard] (https://www.keyclack.com/product/gb-ps2avrgb/), for use on the YMD75, from YMDK. YMDK sell the board and name it "YMD75", however the PCB has "MT84" printed on both sides.
+75% keyboard from YMDK. YMDK sell the board and name it "YMD75", however the PCB has "MT84" printed on both sides.
 
-Most of the code was taken and amended from YMD96 and my port JJ50, which in itself was taken from ps2avrGB and amended by Andrew Novak.
-
-Note that this is a complete replacement for the firmware, so you won't be
-using Bootmapper Client to change any keyboard settings, since not all the
-USB report options are supported.  
-
-Hardware Supported: YMD75/MT84 with the ATmega32a chip.
-Hardware Availability: The YMD75/MT84 PCB is available from YMDK on AliExpress and suchlike.

+* Keyboard Maintainer: [Wayne K Jones](github.com/WarmCatUK)

 Make example for this keyboard (after setting up your build environment):
 
-```
-$ make ymd75:default:program
-```
-It should detect the keyboard and set it to bootloader mode automatically, prior to flashing firmware.
-I've found that I need to remove the previous build/file before making a new one as it doesn't overwrite it; but this might just be my personal experience.
-
-See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
-
-Note that this is a complete replacement for the firmware, so you won't be
-using Bootmapper Client to change any keyboard settings, since not all the
-USB report options are supported.
-In addition you may need the AVR toolchain and `bootloadHID` for flashing:
-
-```
-$ brew cask install crosspack-avr
-$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
-```
-
-In order to use the `./util/atmega32a_program.py` script, which can reboot the board into
-the bootloader, you'll need Python 2 with PyUSB installed:
-
-```
-$ pip install pyusb
-```
-
-If you prefer, you can just build it and flash the firmware directly with
-`bootloadHID` if you boot the board while holding down `Left Control` to keep it
-in the bootloader:
-
-```
-$ make ymd75
-$ bootloadHID -r ymd75_default.hex
-```
-I dont use windows personally, but the following is from ymd96 regarding flashing the atmega32a:
-
-Since the YMD75/MT84 uses an ATmega32a chip instead of the 32u4, you need to download [HIDBootFlash v.1.0](http://vusb.wikidot.com/project:hidbootflash) for Windows. If anyone knows of a Linux/Mac bootflasher that works, edit this readme!
-On Windows, I use [MINGw](http://www.mingw.org/) to compile the keymaps. On Linux or OSX you can simply use the terminal.
-
-Once you have those two pieces of software:
-Build the keyboard with  
-```
-$ make ymd75:default
-```  
-If you make your own layout, change the `default` word to whatever your layout is.  
-
-And flash the compiled hex file with `HIDBootFlash`. Simply put the board in flashing mode by plugging it in while holding the key below the top right key, and click `find device`. Then you can specify the .hex file and flash it to the device.
-
-
-## Troubleshooting
+    make ymd75:default
 
-1. Try plugging the board in while pressing `Backspace` (`Key below the top right key`). This will force it to boot only the bootloader without loading the firmware. Once this is done, just reflash the board with the original firmware.
-2. Sometimes USB hubs can act weird, so try connecting the board directly to your computer or plugging/unplugging the USB hub.
-3. If you get an error such as "Resource Unavailable" when attemting to flash on Linux, you may want to compile and run `tools/usb_detach.c`. See `tools/README.md` for more info.
-4. I was occasionally finding that I wasn't flashing changes that I was making to my keymap. If that happens, remove the previous build and simply force rebuild by making with:
-```
-$ rm ymd75_default.hex
-$ make -B ymd75:default
-$ make -B ymd75:default:program
-```
+Flashing example for this keyboard ([after setting up the bootloadHID flashing environment](https://docs.qmk.fm/#/flashing_bootloadhid))
 
+    make ymd75:default:flash
 
+**Reset Key**: Hold down the key located at *Key below the top right key*, commonly programmed as *Backspace* while plugging in the keyboard.
