I find this statement interesting because I have always thought that stuff like this are too technical for the average ‘end user’ but easy to understand for developers. For context, the only time I interacted with Geth was during a blockchain programming BootCamp (which I dropped out from by the way cos it got too technical for me 
).
When you say ‘plentiful documentation’, do you mean user guides, tutorials, etc?
Also, why do you think documentations for developers were non-existent?
