+# Flask Web Server for Simple Website
+
+This is a simple, expandable Flask web server designed to serve a static website with HTML, CSS, and JavaScript files. The server is designed to be easily expanded with new routes and functionality.
+
+## Setup Instructions
+
+### Prerequisites
+- Python 3.6 or higher
+- pip (Python package manager)
+
+### Installation
+
+1. Install required packages:
+   ```
+   pip install -r requirements.txt
+   ```
+
+### Running the Server
+
+1. Start the Flask development server:
+   ```
+   python app.py
+   ```
+
+2. Access the website at [http://localhost:5000](http://localhost:5000)
+
+## Project Structure
+
+- `app.py` - The main Flask application
+- `requirements.txt` - Python dependencies
+- `index.html` - Main HTML file
+- `css/` - CSS stylesheets
+- `js/` - JavaScript files
+
+## How to Expand the Server
+
+### Adding New Routes
+
+To add a new page or API endpoint, add a route to `app.py`:
+
+```python
+@app.route('/new-page')
+def new_page():
+    return send_from_directory('.', 'new-page.html')
+```
+
+### Adding API Endpoints
+
+For JSON APIs, add a route that returns a JSON response:
+
+```python
+@app.route('/api/data')
+def api_data():
+    data = {
+        'key': 'value',
+        'items': [1, 2, 3]
+    }
+    return jsonify(data)
+```
+
+### Adding Database Support
+
+To add a database, you can use Flask-SQLAlchemy:
+
+1. Install Flask-SQLAlchemy:
+   ```
+   pip install Flask-SQLAlchemy
+   ```
+
+2. Update your `app.py` to include database configuration:
+   ```python
+   from flask_sqlalchemy import SQLAlchemy
+   
+   app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///site.db'
+   db = SQLAlchemy(app)
+   
+   class User(db.Model):
+       id = db.Column(db.Integer, primary_key=True)
+       username = db.Column(db.String(80), unique=True, nullable=False)
+   ```
+
+### Adding User Authentication
+
+For user authentication, you can use Flask-Login:
+
+1. Install Flask-Login:
+   ```
+   pip install Flask-Login
+   ```
+
+2. Configure it in your application:
+   ```python
+   from flask_login import LoginManager, UserMixin
+   
+   login_manager = LoginManager(app)
+   login_manager.login_view = 'login'
+   ```
+
+### Environment Variables
+
+The server passes environment variables to the frontend. To add new environment variables:
+
+1. Update the `get_env_vars()` function in `app.py`:
+   ```python
+   def get_env_vars():
+       return {
+           'thing': 1,
+           'apiUrl': 'http://api.example.com',
+           'newVariable': 'value'
+       }
+   ```
+
+## Production Deployment
+
+For production deployment, consider:
+
+1. Using a WSGI server like Gunicorn:
+   ```
+   pip install gunicorn
+   gunicorn -w 4 -b 0.0.0.0:5000 app:app
+   ```
+
+2. Setting up a proper web server like Nginx as a reverse proxy
+3. Setting environment variables for production configuration
