+// AppConfiguration is a developer-centric definition that describes how to run an App. The application model is built on a decade
+// of experience from AntGroup in operating a large-scale internal developer platform and combines the best ideas and practices from the
+// community.

+// Note: AppConfiguration per se is not a Kusion Module
+//
+// Example:
+// import models.schema.v1 as ac
+// import models.schema.v1.workload as wl
+// import models.schema.v1.workload.container as c
+// import models.schema.v1.workload.container.probe as p
+// import models.schema.v1.monitoring as m
+// import models.schema.v1.database as d
