This is a project you should not follow, since it will be implemented on a ZYBO bord.
This bord is way to complicated to be fun to implement anything on. Field Programable Gate Arrays (FPGAs) are horrible devices to do anything with, since you will be working in either Very highspeed Hardware Descripiton Language (VHDL) witch despite the name is VERY slow to do anything in.
