 # Inventory Components
 
-This page describes the internal components of the inventory application.
+This diagram shows the major internal components of the Inventory Application.
+
+## Purpose
+
+This view breaks the Inventory Application into its main user interface, service, reporting, adjustment, and data access responsibilities. It provides the first detailed component-level view inside a Kell Creations application container.
+
+## Diagram Source
+
+The source for this diagram is maintained as architecture code in:
+
+`architecture/workspace/components-inventory.puml`
+
+## Included Components
+
+- Inventory UI
+- Stock Management Service
+- Material Catalog Service
+- Finished Goods Service
+- Adjustment Service
+- Inventory Reporting Service
+- Inventory Repository
+
+## Connected Shared Services
+
+- Transaction Database
+- Authentication Service
+- Shared Data Repository
+- API Orchestrator
+- Notification Service
+
+## Notes
+
+This component view will later be expanded to align with the detailed design of inventory control, material tracking, stock adjustments, exception handling, and business reporting across the Kell Creations platform.
