GPL icon-license note.

+## How to Run This Application
 
-To run this application, you need to [install `PyQt6`](https://realpython.com/python-pyqt-gui-calculator/#installing-pyqt) on your Python environment. To do that, you can run the following commands in a terminal or command prompt:
+Create and activate a Python virtual environment, then install [PyQt6](https://pypi.org/project/PyQt6/):
 
 ```sh
 $ python3 -m venv ./venv
 $ source venv/bin/activate
-(venv) $ pip install PyQt6
+(venv) $ python -m pip install pyqt6
 ```
 
-Once you have [PyQt](https://www.riverbankcomputing.com/static/Docs/PyQt6/) installed, you can run the application by executing the following command:
+Then launch the sample text editor from the `sample_editor/` directory:
 
 ```sh
 (venv) $ cd sample_editor/
