I know I can’t speak for everyone, but when I was new to drones I couldn’t wait to learn more and to find connections between features and how everything works together… And I regret to inform you the easiest way of doing so is to read documentation. 
If you want a step-by-step guide with an example implementation that is also clearly explained, I recommend to read the How to methodically tune (almost) any multicopter guide. Of course it doesn’t have information about all the possible systems, but it’s quite comprehensive regarding tuning.
