## Scorekeep tutorial

* **Note**\
  If you created and attached custom policies using the prior section of this tutorial, you must remove the policy from the `scorekeepRole` before deleting the CloudFormation stack.

## SQL clients

* **Note**\
  See [Configuring Databases with Elastic Beanstalk](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.db.html) in the *AWS Elastic Beanstalk Developer Guide* for details on how to add a PostgreSQL database to the application environment.

## AWS Lambda functions

* **Note**\
  Running the `random-name` Lambda function requires the creation of additional resources outside of the Elastic Beanstalk environment. See the readme for more information and instructions: [AWS Lambda Integration](https://github.com/awslabs/eb-java-scorekeep/tree/xray/README.md#aws-lambda-integration).
