<a name="use-config-files"></a>

MDAA is configured using YAML configuration files. The main CLI configuration file (typically 'mdaa.yaml') specifies:
+ Global settings
+ Domains
+ Environments
+ Modules to be deployed

Configuration layouts are flexible and can be:
+ Concentrated in a single MDAA config file
+ Spread across multiple config files by domain
+ Organized by line of business
+ Separated by environment
