+## Eliminate Prettier Conflicts for You
+
+[Prettier](https://prettier.io) is a great code formatter, I highly recommend you guys give it a try. This package built-ins the [eslint-config-prettier](https://github.com/prettier/eslint-config-prettier) for you, all you need to do is setup the [Prettier CLI](https://prettier.io/docs/en/cli.html) to use it.
