Dear Inteous....
The bad news is: PID is about the biggest challenge when building a new quad.
The best advice for a noob is: stick with the basic settings that your flightcontroller probides you.
Then learn how to fly, best WITHOUT AUTOLEVEL. Go slowly and take babysteps.
Oneother advice: buy one of those microquads that you can fly indoors without breaking when crashing ... Bucause crashing you WILL do.
Meanwhile, look around the fora about info about PID (oscar liang blog, ...) and learn about it there.
Maybe then, you can try tinkering with it. The learning curve is very steep, IMHO, when diving into PID ...
But in the end you will master the quad
Just my two cents.
One last tip: you can always look out for someone, more experienced then you, that has the same quad, with the same motors, .... And copy their PID-settings, ... And even then you might notice that often PID is also kind of personal preference
