+### Android
+#### AndroidX
 This plugin has been migrated to use [AndroidX (Jetpack)](https://developer.android.com/jetpack/androidx/migrate) which is the successor to the [Android Support Library](https://developer.android.com/topic/libraries/support-library/index).
 This is implemented by adding a dependency on [cordova-plugin-androidx](https://github.com/dpa99c/cordova-plugin-androidx) which enables AndroidX in the Android platform of a Cordova project.

 Therefore if your project includes any plugins which are dependent on the legacy Android Support Library, you should add [cordova-plugin-androidx-adapter](https://github.com/dpa99c/cordova-plugin-androidx-adapter) to your project.
 This plugin will dynamically migrate any plugin code from the Android Support Library to AndroidX equivalents.

 This plugin sets a default minimum iOS version in the Pod file (see `<preference name="IOS_MIN_VERSION">` in `plugin.xml`) which can be overriden using a plugin variable of the same name, e.g.:
 
     cordova plugin add cordova-plugin-firebasex --variable IOS_MIN_VERSION=10.0

+#### Cocoapods
 This plugin depends on [cordova-plugin-cocoapod-supportx](https://github.com/dpa99c/cordova-plugin-cocoapods-support) which adds Cordova support for the [CocoaPods dependency manager]( https://cocoapods.org/) in order to satify the iOS Firebase SDK library dependencies.
 
 Therefore please make sure you have Cocopods installed in your iOS build environemnt - setup instructions can be found [here](https://cocoapods.org/).

+#### Strip debug symbols
+If your iOS app build contains too many debug symbols (i.e. because you include lots of libraries via a Cocoapods), you might get an error (e.g. [issue #28](https://github.com/dpa99c/cordova-plugin-firebase/issues/28)) when you upload your binary to App Store Connect, e.g.:
+
+    ITMS-90381: Too many symbol files - These symbols have no corresponding slice in any binary [16EBC8AC-DAA9-39CF-89EA-6A58EB5A5A2F.symbols, 1B105D69-2039-36A4-A04D-96C1C5BAF235.symbols, 476EACDF-583B-3B29-95B9-253CB41097C8.symbols, 9789B03B-6774-3BC9-A8F0-B9D44B08DCCB.symbols, 983BAE60-D245-3291-9F9C-D25E610846AC.symbols].
+
+To prevent this, you can set the `IOS_STRIP_DEBUG` plugin variable which prevents symbolification of all libraries included via Cocoapods (see here)[https://stackoverflow.com/a/48518656/777265]:
+
+    cordova plugin add cordova-plugin-firebasex --variable IOS_STRIP_DEBUG=true
+
+By default this preference is set to `false`.
+
+Note: if you enable this setting, any crashes that occur within libraries included via Cocopods will not be recorded in Crashlytics or other crash reporting services.
