+# Inspection Reporting and Management Application
+
+A production-ready web application for managing inspection reports, built with Python Flask.
+
+## Features
+
+- User authentication and authorization
+- Admin panel for user management
+- Inspection creation, editing, and viewing
+- Photo uploads with captions and action requirements
+- PDF export of inspection reports (A4 format)
+- Role-based access control (admin vs regular users)
+- Responsive design with Tailwind CSS
+
+## Technology Stack
+
+- **Language**: Python 3.11+
+- **Web Framework**: Flask (with Flask-Login, Flask-WTF, Flask-SQLAlchemy)
+- **Database**: SQLite via SQLAlchemy ORM
+- **PDF Generation**: WeasyPrint
+- **TLS/HTTPS**: Self-signed certificate
+- **Frontend**: Jinja2 templates + Tailwind CSS (via CDN) + vanilla JS
+- **Authentication**: Bcrypt password hashing, session-based login
+- **File Storage**: Local filesystem under `/uploads/`
+
+## Setup
+> **Note**: After running the setup script, an admin user is created with username `admin` and password `admin`. You can change these credentials after logging in.
+
+1. Clone the repository
+2. Run the setup script:
+   ```bash
+   python setup.py
+   ```
+3. The setup script will:
+   - Install dependencies
+   - Generate SSL certificates
+   - Create the database and run migrations
+   - Prompt for admin account details
+4. Start the application:
+   ```bash
+   python run.py
+   ```
+5. Access the application at https://localhost:5000
