| **Quickstart, command line method (Windows/Linux)**

1. Clone the tutorials' repository: 
    - ``git clone https://github.com/harfang3d/tutorials-hg2.git``
2. Enter the repository:
    - ``cd tutorials-hg2``
3. Compile the tutorial resources:
    - ``python3 -m harfang.bin assetc resources``
    - After the compilation process finishes, you should see a ``resources_compiled`` folder next to the resources folder.
4. Run the tutorials:
    - ``D:\tutorials-hg2>python3 draw_lines.py``

| 
| **Quickstart, drag & drop method (Windows)**

1. Download the tutorials https://github.com/harfang3d/tutorials-hg2 and unzip them to your computer (eg. *d:/tutorials-hg2*).
2. To compile the tutorial resources, download **assetc** for your platform: https://dev.harfang3d.com/releases/
3. Drag and drop the tutorial resources folder on the **`assetc** executable -OR- execute **assetc** passing it the path to the tutorial resources folder (eg. *assetc d:/tutorials-hg2/resources*).

After the compilation process finishes, you should see a ``resources_compiled`` folder next to the resources folder. You can now execute the tutorials from the folder you unzipped them to.

    ``D:\tutorials-hg2>python draw_lines.py``

Alternatively you can open the tutorial folder and run the provided debug targets using `Visual Studio Code <https://code.visualstudio.com/>`_
