How to Control 8x8 Led Matrix using 4017 decade counter?


how control 8x8 led matrix using 4017 decade counter, 8 digital arduino outputs, , 8 resistors.
hello, have circuit wired on breadboard, scavenged internet such topic , examples i've seen max chips/micro controllers, , code out there not correspond hardware i'm using. input appreciated!

a quick google search turned tutorial:
http://atmega32-avr.com/make-a-8x10-l-e-d-matrix-using-the-arduino-and-4017-decade-counter/

unless have special 4017 can sink current of 8 leds on each pin need transistor drivers shown in schematic.  if want 8x8 instead of 8x10 leave out last 2 rows.
