+This library comes with a predefined `tslint.json` that tracks the angular cli's config with these changes that we have found useful:
 
 - Disables rules that conflict with Prettier (via [tslint-config-prettier](https://github.com/prettier/tslint-config-prettier))
 - Allows using the `Function` type. Some of our libraries deal a lot with utilities that operate on functions, and using this type is very handy.
