 ===================================
 I wanted to add some features like vi cursor and mouse keys to my [HHKB][HHKB] but its controller is not programmable and
 firmware source code is not open, of course. This means customizing this keyboard needs to replace original 
-controller with programmable one. For this purpose I used PJRC [Teensy++][Teensy] as alternative controller.
+controller with programmable one. This controller can work with HHKB Professional and Professional 2 model.

 ##Features
 * Customizable keymap
 * More keymap layers(more Fn keys)
 * Mouse keys
 * USB NKRO
 
+See README of [tmk_keyboard] for more.

+ 
 ###Pros
+* No risk: Everything is all reversible
 * Without PCB trace cutting, case mod or any destructives
 * Can keep original controller intact
 * Can change all HHKB behaviour as you like
 
 ###Cons
 * Void your warranty
-* Lose USB hub function in case of Pro2
+* Lose USB hub function of Pro2

+##Build Firmware & Program
+You can choose some combination of hardware and USB protocol stack([LUFA], [PJRC]).
 
+### Install Tools
+See [this document](../../doc/build.md).
 
-##Build Firmware
-You can choose some combination of MCU and USB protocol stack.
-
-### Teensy++(AVR USB family) with [LUFA]
-0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
-
-1. Edit **keymap.c** to use your favoirte keymap.
-
-2. Edit **Makefile** if you want to use other `MCU` than Teensy++ 2.0.
+### TMK Alt Controller Board
+    $ make -f Makefile.tmk
 
-3. Build firmware binary file:
-    `$ make -f Makefile.lufa`
+This programs the controller with [dfu-programmer] if the tool is intalled and configured properly.
 
-4. Program MCU with PJRC [Teensy Loader] tool. If you install command line version of the loader just run:
-    `$  make -f Makefile.lufa teensy`
+    $ make -f Makefile.tmk dfu
 
-[LUFA]: http://www.fourwalledcubicle.com/LUFA.php
-[Teensy Loader]: http://www.pjrc.com/teensy/loader.html
+Push reset button and program with [FLIP]. The tool should be intalled and configured properly.
 
+    $ make -f Makefile.tmk flip
 
-###AVR Mega with [V-USB]
-Follow below if you want to use AVR with V-USB as .
+Or you can also program with FLIP GUI.
 
-0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
+[dfu-programmer]: http://dfu-programmer.sourceforge.net/
+[FLIP]: http://www.atmel.com/tools/FLIP.aspx
 
-1. Edit **keymap.c** to use your favoirte keymap.
 
-2. Edit **usbconfig.h** to configure V-USB options. 
+### PJRC Teensy++
+Build with [LUFA] USB stack:
 
-3. Edit **Makefile.vusb** to define `MCU` and `F_CPU`.
+    $ make -f Makefile.lufa
 
-4. Build firmware binary file:
-    `$ make -f Makefile.vusb`
+or with [PJRC] USB stack:
 
-5. Program MCU with AVR programmer like AVRISPmkII. If you already have [USBaspLoader] on MCU just run:
-    `$  make -f Makefile.vusb program`
+    $ make -f Makefile.pjrc
 
-[V-USB]: http://www.obdev.at/products/vusb/index.html
-[USBaspLoader]: http://www.obdev.at/products/vusb/usbasploader.html
+Push reset button and program with [Teensy Loader(command line)]. The tool should be intalled and configured properly.
 
+    $  make -f Makefile.lufa teensy
+    $  make -f Makefile.pjrc teensy
 
-###How to Customize Keymap
-Later...
-See **keymap.c**.
+Or you can also program with [Teensy Loader(GUI)].

-##Hardware
 
-###Teensy++ installation
-Angled USB mini B adapter is used to install Teensy++ laterally.
+###AVR Mega with [V-USB]
+Build:
+    $ make -f Makefile.vusb
 
-![Image of Teensy install](hhkb/doc/HHKB_img/teensy_install.jpg)
+Program [USBaspLoader] on MCU with AVR programmer like [AVRISPmkII] and tool like [avrdude].
 
-Bread baord wires are used to connect Teensy++.
+You can programs with [avrdude] once you have programmed [USBaspLoader] on MCU.
+    $  make -f Makefile.vusb program
