-Build
-=====
-PJRC Teensy
------------
-0. Edit matrix.c.
-    adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
-1. Define macros in config_pjrc.h.(Optional)
-    VENDOR_ID, PRODUCT_ID and string descriptor.
-    IS_COMMAND
-2. Edit Makefile for MCU setting and build options.
-    MCU, F_CPU
-    MOUSEKEY_ENABLE, EXTRAKEY_ENABLE, NKRO_ENABLE
-3. Build hex file.
-    $ make -f Makefile.pjrc
-4. Program MCU.
-    $  make -f Makefile.pjrc program
-
-
-V-USB
------
-0. Edit matrix.c and usbconfig.h.
-    adjust scan code to your pin configuration.(see doc/HHKB.txt for pinouts)
-    define macros for V-USB in usbconfig.h.
-1. Define macros in config_vusb.h.(Optional)
-    IS_COMMAND
-2. Edit Makefile.vusb for MCU setting and build options.
-    MCU, F_CPU
-    MOUSEKEY_ENABLE, EXTRAKEY_ENABLE
-3. Build hex file.
-    $ make -f Makefile.vusb
-4. Program MCU.
-    $  make -f Makefile.vusb program
-
-    Using a bootloader to program for convenience is recommended.
-    Once program this V-USB bootloader at first, you can program MCU without
-    extra programmer. You should have reset switch to start up as bootloader
-    mode in this case.

+Alternative Controller for HHKB Pro
+===================================
+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.
+
+[HHKB]: http://www.pfu.fujitsu.com/hhkeyboard/
+[Teensy]: http://www.pjrc.com/teensy/
+
+
+My keyboard firmware source tree is here: http://github.com/tmk/tmk_keyboard
+See directory keyboard/hhkb to build firmware for HHKB.
+
+
+##Features
+* Customizable keymap
+* More keymap layers(more Fn keys)
+* Mouse keys
+* USB NKRO
+
+###Pros
+* 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
+
+##DISCLAIMER
+I'm not a professional of electronics or MCU programming. This may damage your HHKB.
+And my English writing is poor, I'm not sure I can convey my notions accurately.
+
+
+
+
+
+
+##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.
+
+3. Build firmware binary file:
+    `$ make -f Makefile.lufa`
+
+4. Program MCU with PJRC [Teensy Loader] tool. If you install command line version of the loader just run:
+    `$  make -f Makefile.lufa teensy`
+
+[LUFA]: http://www.fourwalledcubicle.com/LUFA.php
+[Teensy Loader]: http://www.pjrc.com/teensy/loader.html
+
+
+###AVR Mega with [V-USB]
+Follow below if you want to use AVR with V-USB as .
+
+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 **usbconfig.h** to configure V-USB options. 
+
+3. Edit **Makefile.vusb** to define `MCU` and `F_CPU`.
+
+4. Build firmware binary file:
+    `$ make -f Makefile.vusb`
+
+5. Program MCU with AVR programmer like AVRISPmkII. If you already have [USBaspLoader] on MCU just run:
+    `$  make -f Makefile.vusb program`
+
+[V-USB]: http://www.obdev.at/products/vusb/index.html
+[USBaspLoader]: http://www.obdev.at/products/vusb/usbasploader.html
+
+
+###How to Customize Keymap
+Later...
+See **keymap.c**.
+
+
+##Hardware

+###Teensy++ installation
+Angled USB mini B adapter is used to install Teensy++ laterally.

+Bread baord wires are used to connect Teensy++.

-I used Teensy++ as alternative controller. Though a Teensy has enough ports to drive HHKB,
-Teensy++ has clean pinout and it makes programing and wiring easier.
+Internal of HHKB pro
+=====================
+HHKB pro has MCU and some chips on separate two PCBs.
 
-This is just a proof of concept for replacing controller of HHKB, not a complete firmware.
-
-My prototype firmware source tree is here:
-    github(http://github.com/tmk/tmk_keyboard)
-This firmware is a port of my previous project:
-    HHKB style Mod(http://geekhack.org/showwiki.php?title=Island:11930)
-PJRC:
-    Teensy++/Teensy(http://www.pjrc.com/teensy/)
-
-
-Pros:
-    * without pattern cutting, case mod  and soldering
-    * can keep original controller intact
-    * can change HHKB behaviour as you like(by C programming)
-
-Cons:
-    * void your warranty
-    * unavailability of Teensy++/Teensy(because of PS3 cracking boom?)
-
-Features:
-    * customized keymap
-    * more keymap layers
-    * mouse keys for minimum mouse operation(never comfortable for normal use)
-    * and more...(in the future)

-Any suggestions or ideas are welcome.
