+# Custom Locale Data
+
+This folder is used to store custom locale data. These custom locale data are
+not yet provided by [Unicode Common Locale Data Repository](http://cldr.unicode.org/development/new-cldr-developers)
+and hence not provided in [react-intl/locale-data/*](https://github.com/yahoo/react-intl).
+
+The locale data should support [Locale Data APIs](https://github.com/yahoo/react-intl/wiki/API#locale-data-apis)
+of the react-intl library.
+
+It is recommended to start your custom locale data from this sample English
+locale data:
+
+```javascript
+/*eslint eqeqeq: "off"*/
+/*eslint no-nested-ternary: "off"*/
+
+export default [

+        t = o && n[0].slice(-1),
