+Alternative Controller for HHKB
+===============================
+
+Feature
+-------
+- Mouse Keys
+- NKRO on USB
+- Keymap Layers
+
+
+Customize Keymap
+----------------
+see keymap.c.
+
+
+Build for 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, USB_EXTRA_ENABLE, USB_NKRO_ENABLE
+3. Build hex file.
+    $ make
+4. Program MCU.
+    $  make program
+
+
+Build for 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, USB_EXTRA_ENABLE, USB_NKRO_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.
