+# Java SendGrid email sample for Google Managed VMs
+This sample demonstrates how to use [SendGrid](https://www.sendgrid.com) on Google Managed VMs
+For more information about SendGrid, see their [documentation](https://sendgrid.com/docs/User_Guide/index.html).
+## Setup
+Before you can run or deploy the sample, you will need to do the following:
+1. [Create a SendGrid Account](http://sendgrid.com/partner/google). As of September 2015, Google users start with 25,000 free emails per month.
+1. Configure your SendGrid settings in the environment variables section in ``src/main/appengine/app.yaml``.
+## Running locally
+You can run the application locally and send emails from your local machine. You
+will need to set environment variables before starting your application:
+    $ export SENDGRID_API_KEY=[your-sendgrid-api-key]
+    $ export SENDGRID_SENDER=[your-sendgrid-sender-email-address]
+    $ mvn clean jetty:run
