+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.
+
+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.
+
+This version by Wayne K Jones (github.com/WarmCatUK)
+
+## Installing and Building
+
+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/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) 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 `./program` 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
+
+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
+```
+
+

+General Description:
+This file is an example configuration (with inline documentation) for the USB
+driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
+also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
+wire the lines to any other port, as long as D+ is also wired to INT0 (or any
+other hardware interrupt, as long as it is the highest level interrupt, see
+section at the end of this file).
+*/
+
+/* ---------------------------- Hardware Config ---------------------------- */
+
+#define USB_CFG_IOPORTNAME D

+ * "Optional MCU Description" below, or you can connect D- to the interrupt, as
+ * it is required if you use the USB_COUNT_SOF feature. If you use D- for the

+ * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
+ * information about this function.
+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ * + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ * at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
+ * used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
+ * you want RAM pointers.
+ * + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ * in static memory is in RAM, not in flash memory.
+ * + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ * the driver must know the descriptor's length. The descriptor itself is
+ * found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):
+ * char usbDescriptorDevice[];
+ * char usbDescriptorConfiguration[];
+ * char usbDescriptorHidReport[];
+ * char usbDescriptorString0[];
+ * int usbDescriptorStringVendor[];
+ * int usbDescriptorStringDevice[];
+ * int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
+ *
+ * The following descriptors are defined:
+ * USB_CFG_DESCR_PROPS_DEVICE

+ * USB_CFG_DESCR_PROPS_HID
+ * USB_CFG_DESCR_PROPS_HID_REPORT
+ * USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
+ *
+ * Note about string descriptors: String descriptors are not just strings, they
+ * are Unicode strings prefixed with a 2 byte header. Example:
+ * int serialNumberDescriptor[] = {
+ * USB_STRING_DESCRIPTOR_HEADER(6),
+ * 'S', 'e', 'r', 'i', 'a', 'l'
