 ### Arduino Firmware
 This firmware is mostly for educational purposes.
 Its low level code shows how keyboard firmware works on the electronical/physical level. There is a very [basic version](firmware_arduino/hackpad_simple/hackpad_simple.ino) that only includes the bare minimum to understand the keyboard matrix. The more [advanced version](firmware_arduino/hackpad/hackpad.ino) also includes functionality like debouncing.

 ### QMK Firmware
+[QMK](https://qmk.fm) ([TLA](https://en.wikipedia.org/wiki/Three-letter_acronym) for Quantum Mechanical Keyboard) is an open source community centered around developing computer input devices. It provides a very comprehensive firmware library, which can be customized to different keyboard hardware and layouts without the need to write own code.

 #### Installing and locating QMK on your Computer
 With QMK it is simple to define custom layouts and up to 32 layers.

 The QMK version from the official website, does not yet include the software definitions for the `hackpad`-keyboard, so we need to add it manually.
 For this you need to copy the directory `hackpad` found at [firmware_qmk/hackpad](firmware_qmk) into the `keyboards` directory in the `qmk_firmware` you have downloaded earlier.
 You can get a copy of the `hackpad` directory by downloading this repository and extracting it.

 This is done by running `qmk flash -kb hackpad -km "your keymap name"`, where `"your keymap name"` is the name of the subdirectory in the `keymaps` directory which you want to upload to the keyboard.
