It's understandable that you feel that this community can seem a bit ....elitist... at times, I've seen and felt it too in the past few years of lurking here. What you need to understand though is that there is a metric-ton of information in this forum, whether it's in the guides, worklogs or videos that members post, you just need to look. The long time members can come across as arrogant because they get asked a LOT of the same questions over and over, questions that can be answered with just a little bit of research and patience. Secondly, you say that there should be a start-to-end guide (and maybe there should be) but what you need to remember is this is not a job for a lot of the members here, it's a hobby. Be thankful for the information that is available and not disappointed for the information that's not. Maybe someone will make a full guide at some point but for now people will just need to research, learn, fail and then maybe get good.
