+# <p align="center">Jitsi Meet React Native SDK</p>
+
+
+## Installation
+ Inside your project, run `npm i @jitsi/react-native-sdk`.<br/><br/>Additionally if not already installed, the following dependencies need to be added:
+ <br/>`npm i @react-native-async-storage/async-storage react-native-webrtc`
+
+ [comment]: # (These deps definitely need to be added manually, more could be neccesary)
+
+### iOS
+
+#### Project Info.plist
+- Add a *Privacy - Camera Usage Description*
+- Add a *Privacy - Microphone Usage Description*
+
+#### General
+- Signing & capabilites:
+    - Add Background modes
+        - Audio
+        - Voice over IP
+        - Background fetch
+- Add Copy Sounds step:
+
+```
+    SOUNDS_DIR="${PROJECT_DIR}/../node_modules/rnsdk/sounds"
+    cp $SOUNDS_DIR/* ${CONFIGURATION_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/
+```
+#### Podfile
+- At the beginning of your target step add `pod 'ObjectiveDropboxOfficial', :modular_headers => true`
+
+Run `cd ios && pod install && cd ..`
+
+### Android
+
+- In your build.gradle have at least `minSdkVersion = 24`
+- TODO: HOW TO ADD COPY SOUNDS STEP
+- Under the `</application>`  tag of your AndroidManifest.xml make sure that it includes
+  ```
+    <uses-permission android:name="android.permission.RECORD_AUDIO" />
+    <uses-permission android:name="android.permission.CAMERA" />
+  ```
+
+### TODOS
+- Ref ConnectionService to not rely on ReactInstanceHolder anymore
+- Add Copy Sounds step to build.gradle
+- Include copy sounds step in podspec (if possible)
+- Add ranges for dependencies
+- Add Build_Config for react native to AppInfoModule
