 The default configuration for Spinner environments can be found at [config/spinner.yaml](https://forge.winningsoftware.co.uk/LoomLabs/spinner/src/branch/main/config/spinner.yaml)
 in the Spinner repository.

 # Custom Configuration
 ## Argument Priority
 
+Environment options and arguments are considered in the following priority order:
+
+- Those explicitly passed to the commands via the CLI
+- Any set in the `spinner.yaml` file in your projects root directory
+- Fallback to the default configuration found in this repository at `config/spinner.yaml`
+
+This means that if you were to set `environment.database.enabled: true` in your config file, but pass the 
+`--disable-database` flag when running the `spin:up` command, your projects settings would be overridden by
+the flag you passed in.
