+Skog TKL by Percent
+==========================
+
+Keyboard Maintainer: QMK Community  
+Hardware Supported: Skog PCB  
+Hardware Availability: https://geekhack.org/index.php?topic=87953.0
+
+Make example for this keyboard (after setting up your build environment):
+
+    make skog:default
+
+## Setting the board to bootloader mode
+
+If you're lucky, the programming script does this automagically for you. If
+however this doesn't work for you, you need to enter the bootloader mode manually
+by plugging the keyboard in while holding the bootloader key. If you did this
+correctly the LEDs will blink and you'll be able to flash your firmware.
+
+The bootloader key is in the top-right (Pause).
+
+## Flashing
+
+ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods. 
+
+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. 
+
+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
+    brew install pyusb
+    brew install --HEAD`https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
+
+4. Place your keyboard into reset. 
+5. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file.

+
+## 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.
