 IBM 4704 to USB keyboard converter
-=======----=======================
+==================================
 This firmware converts IBM 4704 keyboard protocol to USB HID.
 
+Keyboard initialization process takes a few seconds at start up. During that you will hear buzzer from the keyboard. **You need to plug USB cable after hooking up your keyboard to the converter.**
 
-Connect Wires
--------------
-In case of Teensy2.0(ATMega32U4):
 
-1. Connect Vcc and GND.
-2. Connect Clock and Data line. 
-    - Clock is on PD1 and Data on PD2.
-3. Optionally you need pull-up register. 1KOhm is OK?

+Connection
+----------
+In case of using ATMega32U4(Teensy2.0):
+
+1. Supply power with VCC and GND.
+2. Connect CLOCK to PD1 and DATA to PD0. You can change pin with config.h.
+3. Optionally you may need pull-up register. 1KOhm probably work.
