-7 Segment Display Driver
-=====================================
+# 7 Segment Display Driver
+> TTL-7447-like implementation for logisim
+
+The 7-segment display driver is an implementation of or BCD (Binary Coded Decimal) to 7-segment display decoder and driver.
+
+It allows you to send binary numbers to a 7 segment display rather than implementing every character yourself.
 
 ## What is Logisim ?
 
-See at the Project page: http://ozark.hendrix.edu/~burch/logisim/
+Logisim is a circuit simulator. More info: http://www.cburch.com/logisim/
