Rookie requires sourdough basic information

Toast

As a fresh-faced rookie baker looking to break into the Sourdough League, I am feeling a wee bit overwhelmed by  the mountain of info available on that subject. Can anyone suggest one or two of the very best, most reliable,  web articles, on TFL or wherever, that will serve to launch my sourdough breaducation? Grazi mille!

I shall start there, then, and promise to let you know the dope on my first wild yeast bread.

I appreciate the quick reply.
