# Customizing the solution


This solution deploys an S3 bucket with six customizable YAML configuration files contained in a single ZIP archive.. The YAML files are pre-populated with a minimal configuration for the solution. You can create an optional seventh configuration file (`customizations-config.yaml`) to define customizations to the core solution. You can customize the YAML configuration files to deploy additional resources and infrastructure to the solution environment. Refer to [Using configuration files](using-configuration-files.md) for more information, and our [sample configuration](https://github.com/awslabs/landing-zone-accelerator-on-aws/tree/main/reference/sample-configurations/lza-sample-config) for an example of sample implementation.
