# SIMULATION MANAGER CONFIGURATION The recommended way to create a local configuration file for the Simulation Manager is through CDF's [installer](../../installer/README.md#deployment-using-wizard). # Configuration for Running Locally Once you had deployed cdf to your AWS account, you can generate `.env` file to be used for your local development The instruction to generate the local file can be found [here](../../installer/README.md#local-development). The `.env` file will be populated with resources and options that are specified during the deployment wizard flow. ```ini # The S3 key prefix where Simulation artifacts will be stored AWS_S3_PREFIX=simulations/ The allowed CORS origin to validate requests against. CORS_ORIGIN=* # Application logging level. Set to (in order) error, warn, info, verbose, debug or silly.
