chromium/ash/webui/recorder_app_ui/resources/components/cra/README.md

This directory contains components that are customized to CrOS Recorder App
need, but still follows the cros component design and could potentially be
upstreamed back to jellybean (except cra-icon).

These could be specific customization of the base cros-components or material
library, or newly written components.

All components in this folder are prefixed with `cra-`.
