since you seem to be between beginner and advanced stage,
i’d recommend you to take a look here:
That’ll be able to answer many questions,
and is definately worth checking back onto,
from time to time,
as it’s also ever-growing.
And who knows,
maybe one day you write an addition to it. 
And while you’re reading,
here’s some nice music to play in the background,
so you keep focused for the stuff you’re actually seeking.
Just make sure to adjust the volume to a comfortable level,
otherwise it’ll become a distraction easily.
Sincerely,
¥’Berioth
