+We are gradually moving the Kibana code base over to Prettier.

+Prettier is set up to run with ESLint, and to add new code paths to Prettier,
+see `.eslintrc.js` in the root of the Kibana repo. This also means that if you
+get ESLint errors related to Prettier, run `node scripts/eslint --fix` from the
