-### What's Next
+## Set up Stackdriver Logging and Error Reporting
+
+Install the Google Cloud libraries for Stackdriver integration:
+
+```sh
+# Set the environment variable below to the local path to your symfony project
+SYMFONY_PROJECT_PATH="/path/to/my-symfony-project"
+cd $SYMFONY_PROJECT_PATH
+composer require google/cloud-logging google/cloud-error-reporting
+```
+
+### Copy over App Engine files
+
+For your Symfony application to integrate with Stackdriver Logging and Error Handling,
+you will need to copy over the `monolog.yaml` config file and the `ExceptionSubscriber.php`
+Exception Subscriber:
+
+```sh
+# clone the Google Cloud Platform PHP samples repo somewhere
+cd /path/to/php-samples
+git clone https://github.com/GoogleCloudPlatform/php-docs-samples
+
+# enter the directory for the symfony framework sample
+cd appengine/php72/symfony-framework/
+
+# copy monolog.yaml into your Symfony project
+cp config/packages/prod/monolog.yaml \
+    $SYMFONY_PROJECT_PATH/config/packages/prod/
+
+# copy ExceptionSubscriber.php into your Symfony project
+cp src/EventSubscriber/ExceptionSubscriber.php \
+    $SYMFONY_PROJECT_PATH/src/EventSubscriber
+```
+
+The two files needed are as follows:
+
+  1. [`config/packages/prod/monolog.yaml`](app/config/packages/prod/monolog.yaml) - Adds Stackdriver Logging to your Monolog configuration.
+  1. [`src/EventSubscriber/ExceptionSubscriber.php`](src/EventSubscriber/ExceptionSubscriber.php) - Event subscriber which sends exceptions to Stackdriver Error Reporting.
+
+If you'd like to test the logging and error reporting, you can also copy over `LoggingController.php`, which
+exposes the routes `/en/logging/notice` and `/en/logging/exception` for ensuring your logs are being sent to
+Stackdriver:
+
+```
+# copy LoggingController.php into your Symfony project
+cp src/Controller/LoggingController.php \
+    $SYMFONY_PROJECT_PATH/src/Controller
+```
+
+  1. [`src/Controller/LoggingController.php`](src/Controller/LoggingController.php) - Controller for testing logging and exceptions.
+
+### View application logs and errors
 
-1. Check out the [Databases and the Doctrine ORM][symfony-doctrine] documentation for Symfony.
-1. View a [Symfony Demo Application][symfony-sample-app] for App Engine Flex.
+Once you've redeployed your application using `gcloud app deploy`, you'll be able to view
+Application logs in the [Stackdriver Logging UI][stackdriver-logging-ui], and errors in
+the [Stackdriver Error Reporting UI][stackdriver-errorreporting-ui]! If you copied over the
+`LoggingController.php` file, you can test this by pointing your browser to
+`https://YOUR_PROJECT_ID.appspot.com/en/logging/notice` and
+`https://YOUR_PROJECT_ID.appspot.com/en/logging/exception`
