+This library is a compatability layer around
+[@oblador/react-native-vector-icons](https://github.com/oblador/react-native-vector-icons)
+to work with the Exponent asset system. If you're using React Native
+without Exponent, you have no need for this library -- carry on! (or
+maybe [check out Exponent](https://getexponent.com/).
