+# Cloud Monitoring Sample
+
+Simple command-line program to demonstrate connecting to the Google
+Monitoring API to retrieve and modify Alerts data.
+
+## Prerequisites to run locally:
+
+    * [Maven 3](https://maven.apache.org)
+    * [GCloud CLI](https://cloud.google.com/sdk/gcloud/)
+    * Create a Cloud project
+
+# Set Up Your Local Dev Environment
+
+Create local credentials by running the following command and following the oauth2 flow:
+
+    gcloud beta auth application-default login
+
+To run:
+
+    * `mvn clean install`
+    * `./manage_alerts_sample.sh <YOUR-PROJECT-ID> <command> <args>
+
+## Running on GCE, GAE, or other environments
+
+On Google App Engine, the credentials should be found automatically.
+
+On Google Compute Engine, the credentials should be found automatically, but require that
+you create the instance with the correct scopes.
+
+    gcloud compute instances create --scopes="https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/compute,https://www.googleapis.com/auth/compute.readonly" test-instance
+
+If you did not create the instance with the right scopes, you can still upload a JSON service
+account and set `GOOGLE_APPLICATION_CREDENTIALS` as described below.
+
+## Using a Service Account
+
+In non-Google Cloud environments, GCE instances created without the correct scopes, or local
+workstations if the `gcloud beta auth application-default login` command fails, use a Service
+Account by doing the following:
+
+* Go to API Manager -> Credentials
+* Click 'New Credentials', and create a Service Account or [click  here](https://console.cloud.google
+.com/project/_/apiui/credential/serviceaccount)
+ Download the JSON for this service account, and set the `GOOGLE_APPLICATION_CREDENTIALS`
+ environment variable to point to the file containing the JSON credentials.
+
+
+    export GOOGLE_APPLICATION_CREDENTIALS=~/Downloads/<project-id>-0123456789abcdef.json
