 ## Configuration
 
-Database connections rely on configurations provided either through environment variables or a specific configuration file. The package anticipates a `database_config` folder in the root directory of any module using this package. This folder should house the configuration files for the databases. Override the `database_config` folder's location by passing a different path to the database classes' constructor.
