For someone that isn't a programmer that is wanting to understand what a script is doing... "Just read the commands" isn't going to work.

It's like speaking English and being given an instruction manual in French and being expected to understand how a machine is working. You will recognise some borrowed words, but you aren't going to understand it.
"Just read the french manual" or "just learn french" aren't going to work for a consumer wanting to get the machine to work.
