+# Sendgrid and Google App Engine Standard (PHP 5.5)
+
+This sample application demonstrates how to use
+[Sendgrid with Google App Engine Standard Environment](https://cloud.google.com/appengine/docs/standard/php/mail/sendgrid).
+
+## Setup
+
+Before running this sample:
+
+1. You will need a [SendGrid account](http://sendgrid.com/partner/google).
+2. Update `SENDGRID_SENDER` and `SENDGRID_API_KEY` in `app.yaml` to match your
+   SendGrid credentials. You can use your account's sandbox domain.
+
+## Prerequisites
+
+- Install [`composer`](https://getcomposer.org)
+- Install dependencies by running:
+
+```sh
+composer install
+```
+
+## Deploy to App Engine
+
+**Prerequisites**
+
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+**Run Locally**
+```sh
+export SENDGRID_APIKEY=your-sendgrid-api-key
+export [email protected]
+php -S localhost:8000 -t .
+```
+
+**Deploy with gcloud**
+```
+gcloud config set project YOUR_PROJECT_ID
+gcloud app deploy
+gcloud app browse
+```
+
+The last command will open `https://{YOUR_PROJECT_ID}.appspot.com/`
+in your browser.
