+This package updates modified React components in the running app for faster
+feedback after changing a file. To be enabled, your app must:
+
+- Use the `hot-module-replacement` package
+- Use React 16.9.0 or newer
+
+This package is disabled in production. It currently only supports the modern web client.

+Learn more in the [React Fast Refresh docs](https://reactnative.dev/docs/fast-refresh)
+
+React Fast Refresh can be disabled by setting the `DISABLE_REACT_FAST_REFRESH` environment variable before starting Meteor.
