+## Best Practices Checklist
+
+We're trying to move away from some deprecated patterns in this codebase. Please
+check if your PR meets these recommendations before asking for a review:
+
+- [ ] Any _new_ files are using TypeScript (`.ts`, `.tsx`).
+- [ ] Avoid `propTypes` and `defaultProps` in any new or modified code.
+- [ ] Tests should use the helpers in `src/testUtils.tsx` (specifically `initializeMocks`)
+- [ ] Do not add new fields to the Redux state/store. Use React Context to share state among multiple components.
+- [ ] Use React Query to load data from REST APIs. See any `apiHooks.ts` in this repo for examples.
+- [ ] All new i18n messages in `messages.ts` files have a `description` for translators to use.
+- [ ] Avoid using `../` in import paths. To import from parent folders, use `@src`, e.g. `import { initializeMocks } from '@src/testUtils';` instead of `from '../../../../testUtils'`
