+Hardware Availability: [Group buy](https://en.zfrontier.com/products/gray-hb85) finished  
 
 Make example for this keyboard (after setting up your build environment):
 
-    make hb85:default
+    make gray_studio/hb85:default
 
-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.
+Flashing
 
+ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods. 
 
-ps2avrGB keyboard firmware
-==========================
+**Reset Key:** To put the HB85 into reset, hold F3 (`K00`) while plugging in. 
 
-This keyboard uses the port of the QMK firmware for boards that are based on the
-ps2avrGB firmware.
+Windows: 
+1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
+2. Place your keyboard into reset. 
+3. Press the `Find Device` button and ensure that your keyboard is found.
+4. Press the `Open .hex File` button and locate the `.hex` file you created.
+5. Press the `Flash Device` button and wait for the process to complete. 
 
-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.
+macOS:
+1. Install homebrew by typing the following:   
+    ```
+    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
+    ```
+2. Install `crosspack-avr`.  
+    ```
+    brew cask install crosspack-avr
+    ```
+3. Install the following packages:
+    ```
+    brew install python
+    pip3 install pyusb
+    brew install --HEAD`https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
 
-## Installing
+4. Place your keyboard into reset. 
+5. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file. 
 
-First, install the requirements. These commands are for OSX, but all you
-need is the AVR toolchain and `bootloadHID` for flashing:
+**Please Note:** You will need to use the `EEP_RST` keycode first, followed by unplugging/replugging the board to get RGB underglow effects to work.
 
-```
-$ brew cask install crosspack-avr
-$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
-$ pip install pyusb
-```
-
-Then, with the keyboard plugged in, simply run this command from the
-`qmk_firmware` directory:
-
-```
-$ make hb85
-$ bootloadHID -r hb85_default.hex
-```
-
-## Setting the board to bootloader mode
-
-Hold the F3 key while plugging the USB cable.
-
-## Troubleshooting
-
-From my experience, it's really hard to brick these boards. But these
-tricks have been useful when it got stuck in a weird scenario.
-
-1. Try plugging the board in while holding the bootloader 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.
