Set up

Download GodotPlayGamesServices.release.aar and GodotPlayGamesServices.gdap from releases page.
Move the plugin configuration file (GodotPlayGamesServices.gdap) and the binary (GodotPlayGamesServices.release.aar) downloaded from the previous step to the Godot project's res://android/plugins directory.
Enable plugin by accessing Project -> Export, Plugins section. Follow the image.
Go to res://android/build directory. Add below lines to AndroidManifest.xml:

    <meta-data android:name="com.google.android.gms.games.APP_ID"
   	    android:value="@string/app_id" />
   
   	<meta-data android:name="com.google.android.gms.version"
   	   android:value="@integer/google_play_services_version"/>

In the same res://android/build directory,(if it is not already created) create res -> values -> Strings.xml. Add below lines to Strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    	<string name="app_id">ADD_YOUR_APP_ID</string>
</resources>

Replace ADD_YOUR_APP_ID with the app id that was generated after following instructions on Setting Up Google Play Games Services

Check demo project. In order demo project to work, replace ADD_YOUR_APP_ID with your own app id, and in Main.gd add your ids for achievements and leaderboards.

Generate plugin .aar file

If there is no release for your Godot version, you need to generate new plugin .aar file.
Follow these instruction: official documentation.

In short follow these steps:

Download AAR library for Android plugins.
Copy .aar file to godot-lib.release/ and rename it to godot-lib.release.aar
Compile the project:

Open command window and cd into PGSGP direcory and run command below
- Windows:
  
  gradlew.bat assembleRelease
- Linux:
  
  ./gradlew assembleRelease
Copy the newly created .aar file to your plugin directory:

app/build/outputs/aar/GodotPlayGamesServices.release.aar to [your godot project]/android/plugins/

  # Initialize plugin by calling init method and passing to it a boolean to enable/disable displaying game pop-ups
  
  var show_popups := true 
  play_games_services.init(show_popups)
  # For enabling saved games functionality use below initialization instead
  # play_games_services.initWithSavedGames(show_popups, "SavedGamesName")
  
  # Connect callbacks (Use only those that you need)
  play_games_services.connect("_on_sign_in_success", self, "_on_sign_in_success") # account_id: String
