 TMK Keyboard Firmware Collection
 ================================
-This is a keyboard firmware with some useful features for Atmel AVR controller.
+This repository includes keyboard and converter firmware projects built with [`tmk_core`][tmk_core] keyboard library.
 
-Source code is available here: <http://github.com/tmk/tmk_keyboard>
+The latest source code is available here: <http://github.com/tmk/tmk_keyboard>
 
 
 Updates
 -------
+#### 2016/06/22
+Some projects were moved from `converter` and `keyboard` to `orphan` directory. Those might be removed in some future but you will be able to access them with `orphans` tag. See <https://github.com/tmk/tmk_keyboard/issues/173>
+
 #### 2016/02/10
 core: flabbergast's Chibios protocol was merged from <https://github.com/flabbergast/tmk_keyboard/tree/chibios> (@72b1668). See [tmk_core/protocol/chibios/README.md](tmk_core/protocol/chibios/README.md). Chibios protocol supports Cortex-M such as STM32 and Kinetis.
