PXE + Kickstart

I thought I made a post about the last time I tried to do PXE booting, but I don't see it.  Now I'm trying to do PXE booting + Kickstart.  Here's the link I found that's been helping me so far: http://www.smtps.net/pxe-kickstart.html .  Problem is, I don't have any experience with NFS, PLUS I'm running CentOS 7. Yeah, this is probably too many things to assimilate at once, but I'm a glutton for punishment.
