+## BootloadHID
+
+BootloadHID is a USB bootloader for AVR microcontrollers. The uploader tool requires no kernel level driver on Windows and can therefore be run without installing any DLLs.
+
+To ensure compatibility with the bootloadHID bootloader, make sure this block is present your `rules.mk`:
+
+    # Bootloader
+    #     This definition is optional, and if your keyboard supports multiple bootloaders of
+    #     different sizes, comment this out, and the correct address will be loaded
+    #     automatically (+60). See bootloader.mk for all options.
+    BOOTLOADER = bootloadHID
+
+Compatible flashers:
+
+* [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash) (recommended Windows GUI)
+* [bootloadhid Command Line](https://www.obdev.at/products/vusb/bootloadhid.html) / `:BootloadHID` in QMK (recommended command line)
+
+Flashing sequence:
+
+1. Enter the bootloader using any of the following methods:
+    * Tap the `RESET` keycode (may not work on all devices)
+    * Hold the salt key while plugging the keyboard in (usually documented within keyboard readme) 
+2. Wait for the OS to detect the device
+3. Flash a .hex file
+4. Reset the device into application mode (may be done automatically)
+
+or:
+
+    make <keyboard>:<keymap>:bootloadHID
+
 ## STM32
 
 All STM32 chips come preloaded with a factory bootloader that cannot be modified nor deleted. Some STM32 chips have bootloaders that do not come with USB programming (e.g. STM32F103) but the process is still the same.

+# BootloadHID Flashing Instructions and Bootloader Information
+
+ps2avr(GB) boards use an ATmega32A microcontroller and a different bootloader. It is not flashable using the regular QMK methods.
+
+General flashing sequence:
+
+1. Enter the bootloader using any of the following methods:
+    * Tap the `RESET` keycode (may not work on all devices)
+    * Hold the salt key while plugging the keyboard in (usually documented within keyboard readme) 
+2. Wait for the OS to detect the device
+3. Flash a .hex file
+4. Reset the device into application mode (may be done automatically)
+
+## bootloadHID Flashing Target
+
+Using the QMK installation script, detailed [here](newbs_getting_started.md), the required bootloadHID tools should be automatically installed.
+
+To flash via the command line, use the target `:bootloadHID` by executing the following command:
+
+    make <keyboard>:<keymap>:bootloadHID
+
+## GUI Flashing
+
+### Windows
+1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
+2. Place your keyboard into reset. 
+3. Ensure the configured VendorID is `16c0` and ProductID is `05df`
+4. Press the `Find Device` button and ensure that your keyboard is found.
+5. Press the `Open .hex File` button and locate the `.hex` file you created.
+6. Press the `Flash Device` button and wait for the process to complete.
+
+## Command Line Flashing
+
+1. Place your keyboard into reset. 
+2. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file.
+
+### Windows Manual Installation
+For MSYS2:
+1. Download the BootloadHID firmware package from https://www.obdev.at/downloads/vusb/bootloadHID.2012-12-08.tar.gz.
+2. Extract contents using a compatible tool, for example 7-Zip.
+3. Add to the MSYS path by copying `commandline/bootloadHID.exe` from the extracted archive to your MSYS2 installation, typically `C:\msys64\usr\bin`.
+
+For native Windows flashing, the `bootloadHID.exe` can be used outside of the MSYS2 environment.
+
+### Linux Manual Installation
+1. Install libusb development dependency:
+    ```bash
+    # This depends on OS - for Debian the following works
+    sudo apt-get install libusb-dev
+    ```
+2. Download the BootloadHID firmware package:
+    ```
+    wget https://www.obdev.at/downloads/vusb/bootloadHID.2012-12-08.tar.gz -O - | tar -xz -C /tmp
+    ```
+3. Build the bootloadHID executable:
+    ```
+    cd /tmp/bootloadHID.2012-12-08/commandline/
+    make
+    sudo cp bootloadHID /usr/local/bin
+    ```
+
+### MacOS Manual Installation
+1. Install Homebrew by typing the following:
+    ```
+    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
+    ```
+2. Install the following packages:
+    ```
+    brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
+    ```

 The `<target>` means the following
 * If no target is given, then it's the same as `all` below
 * `all` compiles as many keyboard/revision/keymap combinations as specified. For example, `make planck/rev4:default` will generate a single .hex, while `make planck/rev4:all` will generate a hex for every keymap available to the planck.

 * `clean`, cleans the build output folders to make sure that everything is built from scratch. Run this before normal compilation if you have some unexplainable problems.

+## BootloadHID
+
+For Bootmapper Client(BMC)/bootloadHID/ATmega32A based boards, when you're ready to compile and flash your firmware, open up your terminal window and run the build command: 
+
+    make <my_keyboard>:<my_keymap>:bootloaderHID
+
+For example, if your keymap is named "xyverz" and you're building a keymap for a jj40, you'll use this command:
+
+    make jj40:xyverz:bootloaderHID
+
+Once the firmware finishes compiling, it will output something like this: 
+
+```
+Linking: .build/jj40_default.elf                                                                   [OK]
+Creating load file for flashing: .build/jj40_default.hex                                           [OK]

+ * The firmware size is fine - 21920/28672 (6752 bytes free)
+```
+
+After it gets to this point, the build script will look for the DFU bootloader every 5 seconds.  It will repeat the following until the device is found or you cancel it. 
+
+```
+Error opening HIDBoot device: The specified device was not found
+Trying again in 5s.
+```
+
+Once it does this, you'll want to reset the controller.  It should then show output similar to this: 
+
+```
+Page size   = 128 (0x80)
+Device size = 32768 (0x8000); 30720 bytes remaining
+Uploading 22016 (0x5600) bytes starting at 0 (0x0)
