+TMK Keyboard Firmware Core Library
+==================================
+This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.
+
+Source code is available here: <https://github.com/tmk/tmk_keyboard/tree/core>
+
+
++Updates
++-------
++#### 2016/02/10
++flabbergast's Chibios protocol was merged from <https://github.com/flabbergast/tmk_keyboard/tree/chibios>. See [protocol/chibios/README.md](protocol/chibios/README.md). Chibios protocol supports Cortex-M such as STM32 and Kinetis.

+Debugging
+--------
+Use PJRC's `hid_listen` to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
+
+You can use xprintf() to display debug info on `hid_listen`, see `common/xprintf.h`.
