Why don't Intellij Idea plugins have getting started pages?

Question

IntelliJ IDEA

It happened more than once: I saw a popular plugin for an idea, but neither on the official page nor on the github there is any tutorial, or there is but in a terrible state.
Examples:
https://github.com/JetBrains/ideavim
https://plugins.jetbrains.com/plugin/8326-generate...

Answer 1

question to the authors of these plugins.
sane authors at least briefly describe in the readme, as a maximum they write separate posts on the side.
