+# Sample Text Editor
+
+A **sample text editor** that shows how to use Qt Designer to create GUI applications.
+
+## How to Run this Application
+
+To run this application, you need to [install `PyQt5`](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:
+
+```sh
+$ python3 -m venv ./venv
+$ source venv/bin/activate
+(venv) $ pip install PyQt5
+```
+
+Once you have [PyQt](https://www.riverbankcomputing.com/static/Docs/PyQt5/) installed, you can run the application by executing the following command:
+
+```sh
+(venv) $ cd sample_editor/
+(venv) $ python app.py
+```
+
+This command will launch the application, so you'll be able to experiment with it.
