+/* This application demonstrates the usage of the Analytics Admin API using
+service account credentials. For more information on service accounts, see
+https://cloud.google.com/iam/docs/understanding-service-accounts
+
+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.
+https://cloud.google.com/docs/authentication/production#passing_the_path_to_the_service_account_key_in_code
+
+To run this sample using Maven:
+  cd java-analytics-admin/samples/snippets
+  mvn install
+  mvn exec:java -Dexec.mainClass="com.example.analytics.QuickstartSample"
