-# Pearl 40%
-
-Pearl 40% is a keyboard designed by Koobaczech. It uses an Atmel
-ATMEGA32A MCU.
-
-## Compiling and flashing
-
-These instructions are for building and flashing your Pearl 40% without
-Bootmapper Client.
-
-### Requirements
-
-#### Windows
-
-(to be written, help needed)
-
-#### Mac
-
-Apart from regular QMK and AVR dependencies you need to install
-`bootloadHID`. You can install it with `homebrew` as follows:
-
-    $ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
-
-If you don't use `homebrew` you can try following the compiling
-instructions defined below in the Linux section.
-
-#### Linux
-
-For Linux you require all regular QMK dependencies, but make sure you're
-using `gcc-avr` version 4.9 or higher. 4.8 and lower do not contain the
-proper definitions for ATMEGA32A MCUs and QMK will fail while attempting
-to compile a HEX for Pearl 40%.
-
-E.g. you cannot compile Pearl 40% HEX on a regular Ubuntu 14.04 as
-`gcc-avr` version is maxed to 4.8 on it.
-
-Additionally you need an operational `bootloadHID` binary.
-
-You can install `bootloadHID` by taking the following steps:
-
-    $ git clone https://github.com/robertgzr/bootloadHID ~/tmp/bootloadHIDsrc
-    $ cd ~/tmp/bootloadHIDsrc/commandline
-    $ make VENDORID=0x16c0 PRODUCTID=0x05DF # vid and pid for atmega32a
-    $ chmod +x bootloadHID && cp bootloadHID /usr/bin/bootloadHID
-    
-Running `which bootloadHID` should return `/usr/bin/bootloadHID`.
-    
-### Compiling
-
-Enter the QMK root directory and compile a keymap with the following
-command:
-
-    $ make pearl:<keymap>
-    
-where `<keymap>` is a layout directory under the `pearl` directory.
-
-QMK should compile a HEX (called `pearl_<keymap>.hex`) for you, which
-you can flash using `bootloadHID`.
-
-### Flashing
-
-To enable Pearl 40% bootloading mode, unplug the keyboard, then plug it
-in while holding `Esc` at the same time (the top-leftmost switch on the
-PCB, next to the USB connector). Once the board is in bootload mode,
-issue the following command (you might require `sudo` to perform the
-command):
-
-    # assuming we're still in the QMK root dir where you compiled a HEX into
-    $ bootloadHID -r ./pearl_<keymap>.hex
-
-You should see something similar to
-
-    > Page size = <value>
-    > Device size = <value>; <value> remaining
-    > Uploading <value> bytes starting at 0 (0x0)
-    > <value> ... <current value>
-    
-where `<current value>` should be slowly increasing as the HEX is being
-flashed to the board. If there is some warning about `resource busy` it
-should still work OK.
-
-Once done the board underglow should turn red and the new firmware has
-been flashed. If you can't type on the board try plugging it in again
-(without holding any keys to prevent accidentally setting it into
-bootload mode again).
