CNC wood Lathe

I would like to build a CNC wood lathe for my father.
I am an Electrical fitter with machining experience so making the
lathe is no problem.
I would like help in the CNC gear, I have laptop, stepper motors and
driver boards, purchased a kit(K142)from Oatley electronics
(www.oatleyelectronics.com)but they are not much help in getting it
working. Where do I go from here ? Do I purchase software, do I need
other parts ? Could someone please advise me on what to do next?
The more I read, the more confused I get.
