+`yarn link` also installs the `quak` command in yarn's global bin directory, and

+A linked quak uses the dependencies that `yarn install` put in the clone, at the
+versions in quak's `yarn.lock`. Avoid `yarn add file:../quak`: it resolves
+quak's dependencies again, and their newer releases can need a newer Node.
