+
+Provides image loader
+
+# Installation in managed Expo projects
+
+For [managed](https://docs.expo.dev/archive/managed-vs-bare/) Expo projects, please follow the installation instructions in the [API documentation for the latest stable release](#api-documentation). If you follow the link and there is no documentation available then this library is not yet usable within managed projects — it is likely to be included in an upcoming Expo SDK release.
+
+# Installation in bare React Native projects
+
+For bare React Native projects, you must ensure that you have [installed and configured the `expo` package](https://docs.expo.dev/bare/installing-expo-modules/) before continuing.
+
+### Add the package to your npm dependencies
+
+```
+npm install expo-image-loader
+```
+
+### Configure for Android
+
+No additional set up necessary.
+
+# Contributing
+
+Contributions are very welcome! Please refer to guidelines described in the [contributing guide](https://github.com/expo/expo#contributing).
