+# Architecture Workflow
+
+This document defines the standard process for creating, updating, and publishing architecture diagrams and supporting documentation for the Kell Creations Platform.
+
+## Purpose
+
+The goal of this workflow is to ensure:
+
+- Consistent use of C4 modeling across all architecture artifacts
+- Diagram source is maintained as code (PlantUML)
+- Documentation is maintained as code (MkDocs)
+- All changes are version-controlled and auditable
+- Published documentation remains synchronized with source
+
+## Tools and Platforms
+
+- VS Code (Windows 11) — Authoring environment
+- PlantUML Server — https://plantuml.kellsupport.com
+- Forgejo Git — https://git.kellsupport.com
+- MkDocs Material — Documentation framework
+- Docs Site — https://docs.kellsupport.com
+- Ubuntu Server — Build and publishing host
+
+## Architecture Standards
+
+The platform uses C4 modeling:
+
+1. System Landscape
+2. System Context
+3. Container
+4. Component
+
+Supplementary diagrams may include:
+
+- Deployment diagrams
+- Dynamic (sequence/workflow) diagrams
+- Data models
+
+## Directory Structure
+
+- Diagram source:
+  - `architecture/workspace/*.puml`
+
+- Documentation pages:
+  - `docs/architecture/...`
+
+## Workflow Steps
+
+### 1. Create or update diagram (Windows)
+
+- Create or modify `.puml` file in:
+  - `architecture/workspace/`
+- Follow C4 modeling conventions
+- Use shared includes (C4-PlantUML)
+
+### 2. Verify diagram renders (Windows)
+
+- Open `.puml` file in VS Code
+- Press:
+  - `Alt + D`
+- Confirm diagram renders correctly using:
+  - `https://plantuml.kellsupport.com`
+
+### 3. Create or update documentation page (Windows)
+
+- Create or update corresponding Markdown file under:
+  - `docs/architecture/...`
+- Include:
+  - Purpose
+  - Scope
+  - Diagram source reference
+  - Key components or systems
+  - Notes
+
+### 4. Validate repository state (Windows)
