 PS/2 to USB keyboard converter
 ==============================
-This firmware converts PS/2 keyboard protocol to USB and supports only Scan Code Set 2.
-
-
-PS/2 signal handling implementations
-------------------------------------
-Following three methods are used to implement PS/2 signal handling.
-
-### Simple and stupid busy-wait(ps2_busywait.c)
-    This is expected to implemented with portable C code for reference.
-### Interrupt driven(ps2_interrupt.c)
-    Uses pin interrupt to detect falling edge of clock line.
-### USART hardware module(ps2_usart.c)
-    Uses AVR USART engine to recevie PS/2 signal.
-
-To select method edit Makefile.
+This firmware converts PS/2 keyboard protocol to USB.(It supports Scan Code Set 2.)
 
 
 Connect Wires
 -------------
-In case of Teensy2.0(ATMega32U4):
-
-1. Connect Vcc and GND.
-2. Connect Clock and Data line. 
-    - Busywait:    Clock is on PD5 and Data on PD2.
-    - Interrupt:   Clock is on PD1 and Data on PD2.
-    - USART:       Clock is on PD5 and Data on PD2.
-3. Optionally you need pull-up register. 1K-10K Ohm is OK.
+1. Connect **Vcc** and **GND**.
+2. Connect **Clock** and **Data** line. 
+    - **Interrupt**:   **Clock** is on `PD1` and **Data** on `PD0`.(Recommended. Soarer's converter compatible)
+    - **Busywait**:    **Clock** is on `PD1` and **Data** on `PD0`.
+    - **USART**:       **Clock** is on `PD5` and **Data** on `PD2`.
+3. You need pull-up resistors. 1K-10K Ohm would be fine.
 
-To change pin configuration edit config.h.
+To change pin configuration edit **config.h** and **Makefile**.
 
 
-Build Frimware
+Build Firmware
 --------------
-Just run `make`:
+For **TMK converter Rev.2**:
+
+    $ make -f Makefile.rev2 clean
+    $ make -f Makefile.rev2 KEYMAP=plain
 
-    $ make
+To program firmware push the button on converter and run:
 
-To select keymap:
+    $ make -f Makefile.rev2 KEYMAP=plain dfu
 
-    $ make KEYMAP=[plain|jis|spacefn|...]
+
+- For **TMK converter Rev.1** use `make -f Makefile.rev1` instead.
+- To select keymap use `jis`, `spacefn` or your own in place of `plain`.
 
 
 Keymap
 ------
-Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `keymap_<name>.c` and see keymap document(you can find in top README.md) and existent keymap files.

 V-USB Support
 -------------
-You can also use this converter on ATmega(168/328) with V-USB instead of Teensy.
-The converter on V-USB lacks some features for now: USB NKRO and System/Media control.
+With V-USB you can use this converter on ATmega(168/328) but it doesn't support NKRO at this time.
