Setting it up is the smallest part of any competent operation. Capacity planning, monitoring, planning for outages and recovery, updates, backups - including testing for recovery -,… is what takes the effort. Setup is almost always on the happy path. When things go wrong, you start over. But once you have a substantial investment in terms of data stored, that is unlikely to be an option. Now you need to figure out and solve the actual problem, which likely requires intimate knowledge of how the system works. Nobody acquires that knowledge by browsing the quick start installer docs.
