-###### IMPORTANT NOTES
+### Important Notes
+
 - This plugin uses a hook (after prepare) that copies the configuration files to the right place, namely 
 `platforms/ios/my-cordova-project/Resources` for iOS and `platforms/android` for Android.
 - Firebase SDK requires the configuration files to be present and valid, otherwise your app will crash on boot or Firebase features won't work.
 
 ### PhoneGap Build
-Hooks do not work with PhoneGap Build. This means you will have to manually make sure the configuration files are included. One way to do that is to make a private fork of this plugin and replace the placeholder config files (see `src/ios` and `src/android`) with your actual ones, as well as hard coding your app id and api key in `plugin.xml`.

 ### Google Play Services
-Your build may fail if you are installing multiple plugins that use Google Play Services.  This is caused by the plugins installing different versions of the Google Play Services library.  This can be resolved by installing [cordova-android-play-services-gradle-release](https://github.com/dpa99c/cordova-android-play-services-gradle-release).

-If your build is still failing, you can try installing [cordova-android-firebase-gradle-release](https://github.com/dpa99c/cordova-android-firebase-gradle-release).  For more info, read the following [comment](https://github.com/dpa99c/cordova-plugin-request-location-accuracy/issues/50#issuecomment-390025013) about locking down the specific versions for play services and firebase. It is suggested to use `+` instead of `15.+` to ensure the correct versions are used.
