Honestly, I don’t think it’s possible to get by just trusting any particular guide without developing at least some actual understanding of the concepts underlying what you’re doing. The field is just too wide and rapidly changing for any source of info to be authoritative (and stay authoritative indefinitely after the guide is written), so it’s super important to develop the skill of looking up multiple different and possibly conflicting approaches to the task and then synthesizing one that works for your specific situation.
