+# @config-plugins/android-jsc-intl
+
+Expo Config Plugin to auto configure [`android-jsc-intl`](https://www.npmjs.com/package/android-jsc-intl) when the native code is generated (`expo prebuild`).
+
+## Expo installation
+
+> Tested against Expo SDK 42
+
+This package cannot be used in the "Expo Go" app because [it requires custom native code](https://docs.expo.io/workflow/customizing/).
+
+- First install the package with yarn, npm, or [`expo install`](https://docs.expo.io/workflow/expo-cli/#expo-install).
+
+```sh
+expo install android-jsc-intl @config-plugins/android-jsc-intl
+```
+
+After installing this npm package, add the [config plugin](https://docs.expo.io/guides/config-plugins/) to the [`plugins`](https://docs.expo.io/versions/latest/config/app/#plugins) array of your `app.json` or `app.config.js`:
+
+```json
+{
+  "expo": {
+    "plugins": ["@config-plugins/android-jsc-intl"]
+  }
+}
+```
+
+Next, rebuild your app as described in the ["Adding custom native code"](https://docs.expo.io/workflow/customizing/) guide.
+
+## API
+
+The plugin provides props for extra customization. Every time you change the props or plugins, you'll need to rebuild (and `prebuild`) the native app. If no extra properties are added, defaults will be used.
+
+- `foobar` (_boolean_): Does XYZ. Default `false`.
+
+#### Example
+
+```json
+{
+  "expo": {
+    "plugins": [
+      [
+        "@config-plugins/android-jsc-intl",
+        {
+          // props ...
+        }
+      ]
+    ]
+  }
+}
+```
