-1. First, run the PythonPanelService (not part of this repo, provided seperately)
-2. Run the command `poetry run python examples/hello/hello.py`
-3. Open http://localhost:42001/panel-service/panels/hello_panel/ in your browser
-4. If there is an error about missing imports (especially nipanel), execute this
-   command (from the nipanel-python directory) to install the dependencies into the venv: 
-   `%localappdata%\Temp\python_panel_service_venv\Scripts\python.exe -m pip install .\[examples,dev]`,
-    then restart the PythonPanelService and re-run hello.py.

+1. Run the **PythonPanelService** (not part of this repo, provided seperately)
+2. `poetry install --with examples` to get the dependencies needed for the examples
+3. Run the examples with these command(s):
