Why Documentation Saves Teams

Write it down. You'll thank yourself later.

I used to think documentation was something you did after you finished building. Turns out, that mindset doesn't scale.

Documentation is what connects decisions to reasoning. It tells your future teammates why something was done a certain way — and just as importantly, why other things weren't.

Even writing a one-liner in a README helps.

Documentation is like writing a letter to your future self.

Every time I document something, I consider: what question would someone ask me in three months? And I try to answer that ahead of time.
