Frustrations with RHEL Kickstart, how to really get a good grasp on this

At times, it seems like a black box. Shouldn't be this hard. I often feel the official Red Hat documentation is very lacking with solid examples on how to implement correctly (See my post on .discinfo and .treeinfo question, at this point, I'm copying over the files that came with a RHEL 7.4 iso to use with my custom iso).

Can anyone offer pointers or advise on how to learn the syntax for Kickstart.

My end goal is to have a Kickstart file on an SSD drive and have it boot the RHEL installation.
