+# Go Web Server for Simple Website
+
+This is a simple, expandable Go 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
+- Go 1.15 or higher
+
+### Installation
+
+No additional installation is required beyond having Go installed.
+
+### Running the Server
+
+1. Start the Go server:
+   ```
+   go run main.go
+   ```
+
+   Options:
+   - `--port=8080` - Change the port (default: 5000)
+   - `--debug=false` - Disable debug mode
+
+2. Access the website at [http://localhost:5000](http://localhost:5000)
+
+## Project Structure
+
+- `main.go` - The main Go web server
+- `index.html` - Main HTML file
+- `css/` - CSS stylesheets
+- `js/` - JavaScript files
+
+## How to Expand the Server
+
+### Adding New Routes
+
+To add a new route, add a handler function in the `main.go` file:
+
+```go
+http.HandleFunc("/new-route", func(w http.ResponseWriter, r *http.Request) {
+    // Your handler code here
+    fmt.Fprintf(w, "This is a new route")
+})
+```
+
+### Adding API Endpoints
+
+For JSON APIs, add a route that returns a JSON response:
+
+```go
+http.HandleFunc("/api/data", func(w http.ResponseWriter, r *http.Request) {
+    data := map[string]interface{}{
+        "key": "value",
+        "items": []int{1, 2, 3},
+    }
+    w.Header().Set("Content-Type", "application/json")
+    json.NewEncoder(w).Encode(data)
+})
+```
+
+### Adding Database Support
+
+To add a database, you can use one of Go's database packages:
+
+1. Add the necessary imports:
+   ```go
+   import (
+       "database/sql"
+       _ "github.com/mattn/go-sqlite3" // For SQLite
+   )
+   ```
+
+2. Create a database connection:
+   ```go
+   db, err := sql.Open("sqlite3", "./database.db")
+   if err != nil {
+       log.Fatal(err)
+   }
+   defer db.Close()
+   ```
+
+3. Use the database in your handlers:
+   ```go
+   http.HandleFunc("/api/users", func(w http.ResponseWriter, r *http.Request) {
+       rows, err := db.Query("SELECT id, name FROM users")
+       if err != nil {
+           http.Error(w, err.Error(), http.StatusInternalServerError)
+           return
+       }
+       defer rows.Close()
+       
+       var users []map[string]interface{}
+       for rows.Next() {
+           var id int
+           var name string
+           rows.Scan(&id, &name)
+           users = append(users, map[string]interface{}{
+               "id": id,
+               "name": name,
+           })
+       }
+       
+       w.Header().Set("Content-Type", "application/json")
+       json.NewEncoder(w).Encode(users)
+   })
+   ```
+
+### Adding User Authentication
+
+For user authentication, you can use middleware:
+
+1. Create an authentication middleware:
+   ```go
+   func authMiddleware(next http.HandlerFunc) http.HandlerFunc {
+       return func(w http.ResponseWriter, r *http.Request) {
+           token := r.Header.Get("Authorization")
+           // Validate token
+           if token == "" {
+               http.Error(w, "Unauthorized", http.StatusUnauthorized)
+               return
+           }
+           // Call the next handler
+           next(w, r)
+       }
+   }
+   ```
+
+2. Use the middleware with your handlers:
+   ```go
+   http.HandleFunc("/api/protected", authMiddleware(func(w http.ResponseWriter, r *http.Request) {
+       // Protected route logic
+   }))
+   ```
+
+### Environment Variables
+
+The server passes environment variables to the frontend. To add new environment variables:
+
+1. Update the `EnvVars` struct in `main.go`:
+   ```go
+   type EnvVars struct {
+       Thing   int    `json:"thing"`
+       ApiUrl  string `json:"apiUrl"`
+       NewVar  string `json:"newVariable"`
+   }
+   ```
+
+2. Update the `getEnvVars` function:
+   ```go
+   func getEnvVars() EnvVars {
+       return EnvVars{
+           Thing:  1,
+           ApiUrl: "http://api.example.com",
+           NewVar: "value",
+       }
+   }
+   ```
+
+## Production Deployment
+
+For production deployment, consider:
+
+1. Building a binary:
+   ```
+   go build -o server main.go
+   ./server --port=8080 --debug=false
+   ```
+
+2. Setting up a proper web server like Nginx as a reverse proxy
+3. Using environment variables for configuration
+4. Implementing proper logging and monitoring

+# 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
