# Demo Project

1. Open a terminal.
2. `cd` to the directory of the [cloned repository from GitHub](https://github.com/echo3Dco/Python-echo3D-SDK).
3. Make sure that `Python 3.8.16` is properly installed by running the command:

```python
python --version.
```

You can also check if `vedo` and `pyrender` are installed by running the command:

```python
pip list
```

3. Run the command:

```python
python main.py [API_KEY] [SECURITY_KEY]
```

where `[API_KEY]` is your echo3D [API key](/quickstart/get-api-key.md), and `[SECURITY_KEY]` is your [security key](/web-console/manage-pages/collections-and-sharing/security.md).

4. A prompt showing a list of available 3D models will appear. 
5. Enter an integer number to choose which 3D models to retrieve and render.
6. A new window will pop up displaying the rendered 3D model.

**All done! 🎉**
