What's the fastest way for a single person to setup a tarp umbrella/leantoo in the rain in a nothern temperate forest?

Lean-tos are hard-sided structures, and are not really meant to be set up quickly. As a hiker and scouter, I and my group carry tarps all the time, and expect rain to greet us wherever we decide to ...
