> This is an internal package.
> That means this is used as a dependency for other, public packages, but
> should not be taken directly as a dependency in your application's `package.json`.

> If you are updating the version of this package, for example to bring in a
> bug-fix, you should do so by updating your application lockfile with
> e.g. `npm up @scope/package` or equivalent command in another
> package manager, rather than taking a direct dependency.
