+# Firebase In-App Messaging
+
+Firebase In-App Messaging helps you engage your app's active users by sending them targeted, contextual
+messages that encourage them to use key app features. React Native Firebase provides support for both native Android
+& iOS integration with a simple JavaScript API.

+
+## Installation
+
+Install this module with Yarn:
+
+```bash
+yarn add @react-native-firebase/fiam
+```
+
+> Integrating manually and not via React Native auto-linking? Check the setup instructions for <Anchor version group href="/android">Android</Anchor> & <Anchor version group href="/ios">iOS</Anchor>.
+
+## Module usage
+
+Once installed, any published campaigns from the [Firebase console](https://console.firebase.google.com/?utm_source=invertase&utm_medium=fiam&utm_campaign=quick_start) 
+are automatically handled and displayed on your users device. The module provides a JavaScript API to allow greater
+control of the displaying of these messages. 
+
+Once installed, import the FIAM package into your project:
+
+```js
+import fiam from '@react-native-firebase/fiam';
+```
+
+The package also provides access to the firebase instance:
+
+```js
+import { firebase } from '@react-native-firebase/fiam';
+```
+
+### Suppressing messages
+
+The Firebase console campaign manager provides a few events to handle when messages are displayed to users. In some 
+situations you may want to handle this manually to only display messages at a chosen time, for example once a user
+has completed an on-boarding process within your app. The `setMessagesDisplaySuppressed` method can be used to 
+achieve this. 
+
+> The suppressed state is not persisted between restarts, so ensure it is called as early as possible.
+
+```js
+import fiam from '@react-native-firebase/fiam';
+
+async function bootstrap() {
+  await fiam().setMessagesDisplaySuppressed(true);
+}
+
+async function onSetup(user) {
+  await setupUser(user);
+  // Allow user to receive messages now setup is complete 
+  fiam().setMessagesDisplaySuppressed(false);
+}
+```
