You can get an idea by looking at the Production systems page (https://polylith.gitbook.io/polylith/conclusion/production-s...) where each column in the first diagram is a project (deployable artifact / service). All components are specified in a single file, like the configuration file for the poly tool itself: (https://github.com/polyfy/polylith/blob/master/projects/poly...).

I try to explain it in the "Bring it all together" section also: https://polylith.gitbook.io/polylith/architecture/bring-it-a...
