+"""Sample command-line program for retrieving Google Cloud Monitoring API data.
+
+Simple command-line program to demonstrate connecting to the Google Cloud
+Monitoring API to retrieve API data, using application default credentials to
+authenticate.
+
+This sample obtains authentication information from its environment via
+application default credentials [1].
+
+If you're not running the sample on Google App Engine or Compute Engine (where
+the environment comes pre-authenticated as a service account), you'll have to
+initialize your environment with credentials the sample can use.
+
+One way to do this is through the cloud console's credentials page [2]. Create
+a new client ID of type 'Service account', and download its JSON key. This will
+be the account the sample authenticates as.
+
+Once you've downloaded the service account's JSON key, you provide it to the
+sample by setting the GOOGLE_APPLICATION_CREDENTIALS environment variable to
+point to the key file:
+
+$ export GOOGLE_APPLICATION_CREDENTIALS=/path/to/json-key.json
