Specifically, AN-1192.
Also don't forget about the Overture Design Guide speadsheet, and the how-to for it.

As a general rule of thumb, bridged amps work well for 8 ohm (or higher) loads, parallel amps work well for 4 ohm (or lower) loads, and a bridged-parallel can work great for 8 ohms or lower. "Or lower" implies you must parallel more chips to handle the increased load, but there is essentially no limit to the number that you can parallel.

Why "minimalist" ? -- there is no benefit, only risk, to omitting a few decoupling capacitors -- the AN-1192 outline is simple and straightforward.
