- Both Hydra-CLI and the generated project files have dependencies that require Node v10.16 or higher
- Hydra stores the substrate data in an external PostgresSQL 12 instance. The scaffolding tool provides a convenient shortcut for running the database instance from a Docker image. In this case the standard docker environment (
