C4-PlantUML Diagrams

Architecture diagrams in C4-PlantUML format. These are the authoritative source for layout-accurate diagrams. The companion c4-diagrams.md in the parent directory keeps Mermaid versions for inline Gitea rendering.

Render in Gitea

Gitea is configured to render .puml files as diagrams. Open any .puml file in the Gitea UI to see the rendered diagram.

Note: plantuml code fences inside Markdown files do not render inline in Gitea — this is a Gitea limitation unrelated to the server configuration. The .md files in this repo use Mermaid for that reason.

Render in VS Code

Install the PlantUML extension (jebbs.plantuml). The project's .vscode/settings.json already points at the shared server:

plantuml.server = http://heim-nas:8500

Open any .puml file and press Alt+D to preview.
