 /* Google Analytics Data API sample quickstart application.
 
-Example usage:
-    dotnet restore
-    dotnet run <GA4 property ID>
+Before you start the application, please review the comments starting with
+"TODO(developer)" and update the code to use correct values.
 
-This application demonstrates the usage of the Analytics Data API using
-service account credentials. For more information on service accounts, see
+This application demonstrates the usage of the Analytics Data API using service
+account credentials.

+Usage:

+  dotnet run

-The following document provides instructions on setting service account
-credentials for your application:
-
-  https://cloud.google.com/docs/authentication/production
-
-In a nutshell, you need to:
-1. Create a service account and download the key JSON file.
-
-https://cloud.google.com/docs/authentication/production#creating_a_service_account
-
-2. Provide service account credentials using one of the following options:
-- set the GOOGLE_APPLICATION_CREDENTIALS environment variable, the API
-client will use the value of this variable to find the service account key
-JSON file.
-
-https://cloud.google.com/docs/authentication/production#setting_the_environment_variable
-
-OR
-- manually pass the path to the service account key JSON file to the API client
-by specifying the keyFilename parameter in the constructor:
