+
+# React Native Firebase JSON Configuration
+
+As part of the many steps we've taken to simplify using Firebase with React Native; React Native Firebase now allows you to configure various options across all its supported Firebase services via a single `firebase.json` file in your project root.
+
+These options are here to replace steps where you'd normally have to make native code changes to your project.
+
+**Supported Platforms:** Android, iOS (via CocoaPods only)
+
+## Structure
+
+All options for React Native Firebase must be placed inside a wrapping `react-native` object. 
+
+**Supported Values**: `boolean`, `string`, `number`
+
+> Nested items inside `"react-native"` are not supported.
+
+### Example
+
+```json
+{
+  "react-native": {
+    "crashlytics_ndk_enabled": true,
+    "crashlytics_debug_enabled": true,
+    "crashlytics_auto_collection_enabled": false,
+    
+    "ml_natural_language_language_id_model" : true,
+    "ml_natural_language_smart_reply_model" : false,
+    
+    "ml_vision_face_model" : true,
+    "ml_vision_image_label_model" : false,
+    "ml_vision_object_detection_model" : true,
+    
+    "messaging_auto_init_enabled": false
+  }
+}
+```
+
+## Non Firebase Usage
+
+You may find it useful to use it for non-Firebase things in your project, e.g:
+
+ - toggling a feature
+ - injecting values into your Android manifest
+ - switching Android source sets
+ - controlling optional dependencies
+ - controlling native dependency versions
+ - customising build time logic
+ - customising runtime logic
+ - switching which podspec to use based
+
+All config items in a `firebase.json` file can be read at every stage of your app's build/run cycle:
+
+ - Android
+   - Inside Gradle build
+   - Inside native code (e.g. Java)
+ - iOS
+   - Inside Script Phases
+   - Inside Pod install (e.g. can be read inside pod specs)
+   - Inside native code (e.g. Objective-C)
+ - JS
+  - Inside your app bundle
+  - RN CLI - Project Config (`react-native.config.js`)
+  - RN CLI - Dependency Config (`react-native.config.js`)
+ 
+ To help you with this we've documented the internal APIs that are accessible at every location:

+
+### Configuring Models
+
+To be able to use the APIs you'll need to enable the models for the APIs you wish to use.
+
+React Native Firebase allows you to configure these in via a `firebase.json` file in your project root.
+
+Add any of the keys indicated below to your JSON file and set them to `true` to enable them. All models and APIs are disabled (`false`) by default.
+
+```json5
+{
+  "react-native": {
+    // Language Identification
+    "ml_natural_language_language_id_model": false,
+    // Smart Replies
+    "ml_natural_language_smart_reply_model": false
+  }
+}
+```
+
+> If you are manually linking on iOS (e.g. not using CocoaPods) then it's up to you to manage these models and dependencies yourself - `firebase.json` support is only for Android and iOS (via Pods).
