+## Compatibility
+It depends on your targetAPI:
+- `targetAPI <= 28`, you are fine ;)
+- `targetAPI == 29`, please enable `requestLegacyExternalStorage` feature for your project :D
+- `targetAPI >= 30`, don't use this lib. We don't support scope storage for now :(
+    - Unless Google release new external permission or other new feature, we would not consider support scope storage. (or says: "I can't do this")
+    - Or, ofcouse, you are welcome for give us some ideas. Just create a new issues.

+## 兼容性
+这取决于您的 targetAPI ：
+
+- `targetAPI <= 28`，完全没有问题 ;）
+- `targetAPI == 29`，请为您的项目启用 `requestLegacyExternalStorage` 特性：D
+- `targetAPI> = 30`，请勿使用此库。 我们暂时不支持 Scope Storage :(
+     - 除非 Google 发布新的外部存储权限或其他新 API，否则我们不会考虑支持范围存储。 （换句话说：“我太菜了，我做不到”）
+     - 当然，欢迎您给我们一些建议！
