Looking for GI yafray tutorial

I searched for a while now but still i was unable to find a good tutorial for my purposes: architectural viz with GI and photons, so that i get proper exterior lighting and interior indirect lighting. Any link is MUCH appreciated, thanks!

Yafray.org is always your #1 resource for such questions.

Look here for a specific lighting tutorial and for other stuff look in the general Docs
Hope this helps you!
