+# SurveyJS + Python/Flask Demo Example
+
+This demo shows how to integrate [SurveyJS](https://surveyjs.io/) components with a Python/Flask backend.
+
+[View Demo Online](https://surveyjs-flask.azurewebsites.net/)
+
+## Disclaimer
+
+This demo must not be used as a real service as it doesn't cover such real-world survey service aspects as authentication, authorization, user management, access levels, and different security issues. These aspects are covered by backend-specific articles, forums, and documentation.
+
+## Run the Application
+
+Install [NodeJS](https://nodejs.org/) on your machine. After that, run the following commands:
+
+```bash
+git clone https://github.com/surveyjs/surveyjs-flask.git
+cd surveyjs-flask
+
+# python -m venv .venv # create venv in working folder if needed - windows
+# python3 -m venv .venv # macos/linux
+pip install -r requirements.txt
+
+```
+
+Open http://localhost:5000 in your web browser.
+
+## Client-Side App
+
+The client-side part is the `surveyjs-react-client` React application. The current project includes only the application's build artifacts. Refer to the [surveyjs-react-client](https://github.com/surveyjs/surveyjs-react-client) repo for full code and information about the application.
