 C4-PlantUML combines the benefits of [PlantUML](https://plantuml.com/) and the [C4 model](https://c4model.com/) for providing a simple way of describing and communicate software architectures – especially during up-front design sessions – with an intuitive language using open source and platform independent tools.

+## Version information
+
+Starting with v.2.3.2beta1 C4-PlantUML offers version information like PlantUML with its `%version()` call.
+
+* `C4Version()`: Current C4-PlantUML version (e.g. "2.3.2beta1").
+* `C4VersionDetails()`: (Floating) version details with the current PlantUML and C4-PlantUML version (with the alias C4VersionDetailsArea)

 ## Snippets for Visual Studio Code
 
 Because the PlantUML support inside of Visual Studio Code is excellent with the [PlantUML extension](https://marketplace.visualstudio.com/items?itemName=jebbs.plantuml), you can also find VS Code snippets for C4-PlantUML at [.vscode/C4.code-snippets](.vscode/C4.code-snippets).
