# Usage

## Launching TOSCA Designer

1. Open Modelio 5.4.1.
2. Open or create a UML project.
3. Ensure the TOSCA Designer module is installed for the project (`Configuration > Install a module in this project`).

## Creating a Topology Template

- Use the module's graphical editors to define node types, relationship types, and policies.
- Save exports via the module menus to `.tosca` or `.csar`.

## Importing Example Projects

- `File > Import project` then select one of the example zips included in the release.

## Troubleshooting

- If the module doesn't appear in the module catalog, ensure your `.jmdac` is compatible with Modelio 5.4.1 and that Java 8 is active.
