 * `id`: The MMKV instance's ID. If you want to use multiple instances, use different IDs. For example, you can separate the global app's storage and a logged-in user's storage. (required if `path` or `encryptionKey` fields are specified, otherwise defaults to: `'mmkv.default'`)
 * `path`: The MMKV instance's root path. By default, MMKV stores file inside `$(Documents)/mmkv/`. You can customize MMKV's root directory on MMKV initialization (documentation: [iOS](https://github.com/Tencent/MMKV/wiki/iOS_advance#customize-location) / [Android](https://github.com/Tencent/MMKV/wiki/android_advance#customize-location))
 * `encryptionKey`: The MMKV instance's encryption/decryption key. By default, MMKV stores all key-values in plain text on file, relying on iOS's/Android's sandbox to make sure the file is encrypted. Should you worry about information leaking, you can choose to encrypt MMKV. (documentation: [iOS](https://github.com/Tencent/MMKV/wiki/iOS_advance#encryption) / [Android](https://github.com/Tencent/MMKV/wiki/android_advance#encryption))
+* `mode`:  *Android Only*: The MMKV mode. It is set to `single-process` by default. You can set its value to `multi-process` to support simultaneous read-write access between processus at the cost of performance. This is useful when you want to share data between your react-native app and native extensions such as widgets. _Notice_: On iOS, this will automatically be set to `multi-process` if you set an AppGroup in the plist configuration (more information on AppGroups [here](https://github.com/mrousavy/react-native-mmkv/tree/master#app-groups))
