The full set of published specifications is summarized in the table below.

Integrations of the YAML layouts have been created for various content management systems. These include WordPress, LifeType, TYPO3, Joomla, xt: Commerce and Drupal. [4]
It uses YAML files to configure the application's services and performs the creation and start-up process of all the containers with a single command.
