 ## Hermes engine
 
+**Note**: React-native will set Hermes as default engine from `0.70` to instead of JSCore. Please see [official documentation](https://reactnative.dev/blog/2022/07/08/hermes-as-the-default) to get some details.

+### Expo Hermes

+Expo app is supporting Hermes Engine.
+
+You can add or remove `"jsEngine": "hermes"` in `app.json` to enable or disable Hermes Engine. And any changes for app engine you need to run `eas build` to rebuild your application.
+
+```json
+{
+  "expo": {
+    "jsEngine": "hermes"
+  }
+}
+```
+
+**Note**: You maybe need to create developer account to run `eas build`. Any other issue or limitiation, please see [expo hermes ducomentation](https://docs.expo.dev/guides/using-hermes/).
