We are not all programmers

It's free. You get what you pay for. Yelling at the developers because they hit your pet peeve is not a good idea.

Instead of that rant, asking what those things mean and then writing good documentation would have been a much better use of their time. Or just some research, even.

When I'm doing something new (and I do that a lot... I tend to start new hobbies all the time) I don't rant at people for not explaining things to me. Instead, I do a lot of research and experimentation. As a last resort, I politely ask questions, first of friends and family, then of strangers on the internet. It's just polite.

"Spend it, cheapskate."
