The Complete Beginner's Completely Incomplete Guide to Oxygen Not Included

Dupes are so ridiculously cute they make puppies seem grotesque by comparison. And, like puppies, leaving dupes unsupervised will at best lead to yellow puddles in your clean water supply and at worst to inexplicable suffocation and death.

I will avoid speculation as to the reasons behind the inherent death-wish of dupes. (We must convince ourselves it is nothing to do with us and move on.) What I will do instead is provide a beginner-friendly approach to minimizing the amount of yellow in your water storage.
