Here are a few to get you started.
These articles are short, discuss basics and are pretty much to the point.
When it comes down to it, each has their own opinion and each boat and sail configuration may be a bit different.
That means one must do a bit of "experimentation" to dial in their own rig.
It seems some sailors are gear heads that fuss with everything on the boat always and don't necessarily stop to enjoy the sun on their face and the wind in their hair.
Others just sail and tweek here and there, while enjoying the magic of sun, wind, water and a boat.
A search brings up many different discussion snippets, but these articles are pretty good:
