+Apply the plugin in your app's build.gradle.kts:
+
+```
+plugins {
+    id("com.google.gms.google-services" version "5.0.0"
+}
+```
 
+Or in build.gradle:
 ```
 plugins {
-    id 'com.google.gms.google-services' version '4.3.15'
+    id 'com.google.gms.google-services' version '5.0.0'
+}
+```
+
+### New in version 5.0.0 
+
+#### `google-services.json` location
+
+Place the `google-services.json` file for your project in the `app/` directory.
+
+Alternatively, you can use variant specific source-sets, for example: 
+`debug/google-services.json`.
+
+#### Compatible Android plugins
+
+The `com.google.gms.google-services` plugin can only be applied to projects with 
+`com.android.application` or `com.android.dynamic-feature`, as it requires an `applicationId` 
+to function.
+
+The plugin is not compatible with plugins such as `com.android.library` that do not 
+contain an `applicationId`.
+
+#### Plugin configuration
+
+Configure the plugin's behavior through the `googleServices` block in build.gradle.kts:
+
+```
+googleServices {
+    // Disables checking of Google Play Services dependencies compatibility
+    // Default: false
+    
+    disableVersionCheck = true 
+    
+    // Choose the behavior when google-services.json is missing:
+    // Default: MissingGoogleServicesStrategy.ERROR
+    // Possible options: IGNORE, WARN, ERROR  
+    
+    missingGoogleServicesStrategy = MissingGoogleServicesStrategy.WARN
 }
 ```
 
+You can use `missingGoogleServicesStrategy` when some variants in your project
+do not require Google Play Services and are missing the `google-services.json` file.
+
+#### Android Gradle plugin compatibility
+
+The Google Services plugin requires AGP 7.3.0 or newer to work. 
+
 ## Legacy way
 
 Add the following to your buildscript classpath, obtained from Google’s
 [Maven repository](//developer.android.com/studio/build/dependencies#google-maven):
 
 ```
-classpath 'com.google.gms:google-services:4.3.15'
+classpath 'com.google.gms:google-services:5.0.0'
 ```
 
 Apply the plugin in your app's build.gradle:
