I haven't read the article but from the title and header alone, it already reminded me my experience of hosting Lemmy with 0 experience with self hosting. I learned how to start a docker and host a very basic stuff according to docker tutorial, no issue, but as i venture into hosting Lemmy where people keep saying "it's very easy!", i keep failing to do so because the tutorial itself written with a lot of jargon and also missing step (i remember running into a part where the tutorial asked me to just fill in necessary stuff. Which necessary stuff???), i eventually given up. Not sure if they rewrite it recently but i can't be bother with these anymore.
The point here i assume is sometime dev with tons of experience expect people to know what they know, and then written stuff in heavy jargon for the basic tutorial. It's a curse of knowledge.
