# variables.md

> Every system is made of variables.

Every program, every model, every experiment starts the same way: name the
things that change. `variables.md` is the rare domain that says exactly one
thing and says it in the language developers already write documentation in.

A natural home for a data-science handbook, a feature-flag product, an
experiment-tracking tool, or a config-management project.
