       Every change to how the code behaves comes with a new or updated test

       A change to what an operator or user sees, such as a command, flag,
       option, endpoint, service or default, updates the matching page under
-      docs/ or the crate's README in the same diff. For a nix option whose
-      own default, type or meaning changes, an updated `description` on that
-      option counts as the documentation. It does not cover a change in what
-      a service does for operators across hosts, such as what it scrapes,
-      serves or publishes: that needs a docs/ page or README. A nix option
-      declared `internal = true` or `visible = false` is not something an
-      operator sees, so adding or changing one needs none of these.
