It's not you, who is stupid. You have to already be knowledgeable about coding to begin with to understand what developer talks about. But even that is not enough, you are supposed to look up example files and try to figure out yourself, a lot of things readme simply does not mention, it's something you have to get from people who have figured it out already.
I'm currently trying to figure things out this way, may be i will write comprehensive guide on modding for people with no knowledge of IT.
