+CONTRIBUTING
+
+Development setup
+-----------------
+This repository builds a Modelio 5.4.1 module (ToscaDesigner) and requires Java 8 for runtime compatibility with Modelio.
+
+Requirements
+- Java 8 JDK (for running Modelio and for building modules targeting Modelio)
+- Maven 3.6+
+
+Build instructions
+------------------
+From the project root:
+
+```powershell
+mvn -B -DskipTests package
+```
+
+This produces `target/toscadesigner-<version>.jar` and `target/ToscaDesigner_<version>.jmdac`.
+
+Notes
+-----
+- The project compiles with `maven-compiler-plugin` configured to `<release>8` to ensure bytecode compatibility with Modelio 5.4.1.
+- The `MDAKit` dependency is provided by the Modelio runtime; it is declared with `scope=provided` in `pom.xml`.
+- If you need to run checks that require the Modelio API, install Modelio and run integration steps inside its environment.
+
+Contributing
+------------
+- Fork the repo and create a feature branch.
+- Run the build locally and open a pull request.
+- For major changes, open an issue first to discuss the design.
+
+CI
+--
+A GitHub Actions workflow (maven-java8.yml) is included to build with Java 8 on push and pull requests.

+--
+A GitHub Actions workflow (`.github/workflows/maven-java8.yml`) is included. Note:
+
+- The workflow runs Maven under Java 11 so Modelio-related Maven plugins (which require
+	a newer JDK) can execute. The project is still compiled to Java 8 bytecode via the
+	`maven-compiler-plugin` configuration (`<release>8`).
+
+This preserves runtime compatibility with Modelio 5.4.1 while allowing plugin execution
+that needs a newer JDK.
