## 📝 Notes

1. **.env.example** file creation was attempted but filtered by globalignore. The content is ready and should be manually created if needed.

2. **Optional Dependencies**: Some features require optional dependencies (Redis, PostgreSQL, etc.) which are listed in requirements.txt but can work without them using fallbacks.

3. **Database**: The application defaults to SQLite but supports PostgreSQL and MySQL through DATABASE_URL configuration.

4. **Testing**: All test files are created. Run `pytest` to execute tests.

5. **Docker**: Full Docker support with docker-compose for production deployment including PostgreSQL and Redis.
