+# Cloud SQL & Google App Engine
+
+This sample application demonstrates how to use [Cloud SQL with Google App Engine](https://cloud.google.com/appengine/docs/php/cloud-sql/).
+
+## Setup
+
+Before running this sample:
+
+## Prerequisites
+
+- Install [`composer`](https://getcomposer.org)
+- Install dependencies by running:
+
+```sh
+composer install
+```
+
+## Setup
+
+Before you can run or deploy the sample, you will need to do the following:
+
+1. Create a [First Generation Cloud SQL](https://cloud.google.com/sql/docs/create-instance) instance. You can do this from the [Cloud Console](https://console.developers.google.com) or via the [Cloud SDK](https://cloud.google.com/sdk). To create it via the SDK use the following command:
+
+        $ gcloud sql instances create YOUR_INSTANCE_NAME
+
+1. Set the root password on your Cloud SQL instance:
+
+        $ gcloud sql instances set-root-password YOUR_INSTANCE_NAME --password YOUR_INSTANCE_ROOT_PASSWORD
+
+1. Update the connection string in `app.yaml` with your configuration values. These values are used when the application is deployed.
+
+## Run locally
+
+To run locally, you can either run your own MySQL server locally and set the connection string in `app.yaml`, or you can [connect to your CloudSQL instance externally](https://cloud.google.com/sql/docs/external#appaccess).
+
+```sh
+cd php-docs-samples/appengine/standard/cloudsql
+
+# set local mysql connection parameters
+export MYSQL_DSN="mysql:host=127.0.0.1;port=3306;dbname=guestbook"
+export MYSQL_USERNAME=root
+export MYSQL_PASSWORD=
+
+php -S localhost:8080
+```
+
+> be sure the `MYSQL_` environment variables are appropriate for your mysql instance
+
+Now you can view the app running at [http://localhost:8080](http://localhost:8080)
+in your browser.
+
+## Deploy to App Engine
+
+**Prerequisites**
+
+- Install the [Google Cloud SDK](https://developers.google.com/cloud/sdk/).
+
+**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.
+
+## Create the MySQL Tables
+
+Once your application is running, browse to `/create_table` to create the required tables for this example.
