+## Running examples
+
+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.
+
+You can see all running panels (and stop them) at: http://localhost:42001/panel-service/

 # Debugging on the streamlit side
 
 Debugging the measurement script can be done using standard Python debugging
