 Arduino Sketch to simulate a Apple II ASCII Keyboard
 
+![Apple II USB Keyboard Interface](https://github.com/mafrmt00/Apple_II_Keyboard/blob/master/pictures/Keyb_Adapter.jpg "The assembled interface")
+
+### Needed Hardware and Software
+
 Hardware:
   - [Arduino Uno](https://en.wikipedia.org/wiki/Arduino_Uno)
   - [Arduino USB Host Shield](https://www.elecrow.com/wiki/index.php?title=USB_Host_Shield_for_Arduino
 )
   - optional [Arduino Proto Board](https://store.arduino.cc/proto-shield-rev3-uno-size) with DIP Socket
+  - Compatible USB keyboard. Tested with a Logitech K120.
 
-Tghis Table shows how to connect the Apple II Keyboard Connector (A7) to the Arduino. The Pin definitions can also be changed in II_Encoder.h
+Software:
+  - Arduino IDE
+  - USB Host Shield Library 2.0 (The modified Version included in theis Repo!)
+  
+### Installation
+  - Create a folder "Apple_II_Keyboard" under your sketches dir and copy all files from the root dir of this repo there (The dir where the .inop lies). 
+  - Copy the "USB_Host_Shield_Library_2.0" dir to you libraries dir.
+  - Select Uno as board in the Arduino IDE
+  - Use Upload in the Arduino IDE. If you can see some output in the serial monitor as you type everythin works.
