Update README with Ubuntu installer instructions and nginx large file upload configuration

- Add fallback for chown failure by using group permissions
- Add www-data to user's group and set appropriate group permissions
- This handles cases where chown is not permitted (e.g., certain filesystems)

+# Microsoft Entra Authentication Setup Guide
+
+This application uses Microsoft Entra (Azure Active Directory) for authentication. Follow these steps to configure it:
+
+## 1. Create an Azure AD App Registration
+
+1. Go to the [Azure Portal](https://portal.azure.com)
+2. Navigate to **Azure Active Directory** > **App registrations**
+3. Click **New registration**
+4. Enter a name for your app (e.g., "PDF Processor")
+5. For **Supported account types**, select "Accounts in this organizational directory only"
+6. For **Redirect URI**, select "Web" and enter: `http://localhost:5000/auth/callback`
+7. Click **Register**
+
+## 2. Configure Authentication
+
+1. In your app registration, go to **Authentication**
+2. Under **Redirect URIs**, ensure `http://localhost:5000/auth/callback` is listed
+3. Under **Implicit grant and hybrid flows**, check:
+   - [x] Access tokens
+   - [x] ID tokens
+4. Click **Save**
+
+## 3. Get Application Credentials
+
+1. Go to **Overview** in your app registration
+2. Copy the **Application (client) ID** - this is your `AZURE_CLIENT_ID`
+3. Copy the **Directory (tenant) ID** - this is your `AZURE_TENANT_ID`
+
+## 4. Create a Client Secret
+
+1. Go to **Certificates & secrets**
+2. Click **New client secret**
+3. Enter a description and select an expiration
+4. Click **Add**
+5. **Important**: Copy the secret value immediately - this is your `AZURE_CLIENT_SECRET`
+
+## 5. Configure API Permissions
+
+1. Go to **API permissions**
+2. Click **Add a permission**
+3. Select **Microsoft Graph**
+4. Select **Delegated permissions**
+5. Add these permissions:
+   - `openid`
+   - `profile`
+   - `email`
+6. Click **Add permissions**
+7. Click **Grant admin consent** for your organization
+
+## 6. Configure Environment Variables
+
+Create a `.env` file in the project root with your Azure AD settings:
+
+```env
+# Azure AD Configuration
+AZURE_TENANT_ID=your-tenant-id-here
+AZURE_CLIENT_ID=your-client-id-here
+AZURE_CLIENT_SECRET=your-client-secret-here
+AZURE_AUTHORITY=https://login.microsoftonline.com/your-tenant-id-here
+AZURE_REDIRECT_URI=http://localhost:5000/auth/callback
+AZURE_SCOPES=openid profile email
+```
+
+## 7. Update Redirect URI for Production
+
+When deploying to production, update the redirect URI in both:
+- Azure AD app registration
+- Your `.env` file (change localhost to your production domain)
+
+**Note**: For local development, the app runs on port 5000, so use `http://localhost:5000/auth/callback` as the redirect URI.
+
+## 8. Test the Authentication
+
+1. Start the application: `python app.py`
+2. Visit `http://localhost:5000`
+3. Click "Login with Microsoft"
+4. You should be redirected to Microsoft login
+5. After authentication, you'll be redirected back to the app
+
+## Troubleshooting
+
+- **"invalid_client" error**: Check your client ID and secret
+- **"invalid_request" error**: Verify the redirect URI matches exactly
+- **Permission denied**: Ensure you've granted admin consent for the API permissions
+- **Token errors**: Check that your tenant ID is correct
+
+## Security Notes
+
+- Never commit the `.env` file to version control
+- Use strong client secrets and rotate them regularly
+- In production, use HTTPS for all authentication flows
+- Consider implementing token refresh logic for long-running sessions

-# EOY PDF Sortandmerge
+# End of Year Statements PDF Processor
 
-Project to sort, filter, and merge pdf files. 
+A web application for sorting and merging PDF statements by address and page count, optimized for processing large batches of documents.
+
+## Features
+
+- Upload individual PDFs, ZIP archives, or entire folders
+- Automatic address extraction and sorting
+- Parallel processing for maximum speed
+- Real-time progress tracking
+- Web-based interface with progress bars and status updates
+- Asynchronous processing to prevent timeouts
+- **Microsoft Entra (Azure AD) authentication for secure access**
+
+## Authentication
+
+This application requires Microsoft Entra (Azure Active Directory) authentication. Before running the application, you must:
+
+1. Set up an Azure AD app registration
+2. Configure authentication settings in `.env`
+3. Grant necessary API permissions
+
+See [AZURE_AD_SETUP.md](AZURE_AD_SETUP.md) for detailed setup instructions.
+
+## Server Recommendations
+
+### VMware Virtual Machine Specifications
+
+For optimal performance with large PDF batches (1000+ files), we recommend the following VM configuration:
+
+#### Minimum Requirements
+- **vCPUs**: 4 cores
+- **RAM**: 8 GB
+- **Storage**: 50 GB SSD
+- **OS**: Ubuntu Server 22.04 LTS (or CentOS 8+)
+
+#### Recommended for Production
+- **vCPUs**: 8-16 cores (more cores = faster processing)
+- **RAM**: 16-32 GB (PDFs load into memory)
+- **Storage**: 100 GB NVMe SSD
+- **Network**: 1 Gbps connection
+
+#### High-Performance Setup (for 5000+ PDFs)
+- **vCPUs**: 16-32 cores
+- **RAM**: 64 GB
+- **Storage**: 200 GB NVMe SSD
+- **OS**: Ubuntu Server 22.04 LTS
+
+### VMware Configuration Tips
+1. Enable CPU hot-add and memory hot-plug for future upgrades
+2. Use VMXNET3 network adapter for better performance
+3. Allocate storage from a high-performance datastore
+4. Enable VMware Tools for optimal integration
+
+## Installation Instructions
+
+### Option 1: Automated Ubuntu Installation (Recommended)
+
+For Ubuntu servers, use the automated installation script that handles all dependencies, nginx configuration, and permissions:
+
+```bash
+# Download and run the installer
+wget https://gitlab.com/trbc-dev/eoy-pdf-sortandmerge/-/raw/web-app/ubuntu-install.sh
+chmod +x ubuntu-install.sh
+./ubuntu-install.sh
+```
+
+The installer will:
+- Install Python, nginx, and all dependencies
+- Configure nginx with large file upload support (up to 100GB)
+- Set up systemd service for automatic startup
+- Configure Azure AD authentication
+- Set proper file permissions for static assets
+- Generate SSL certificates (optional)
+
+**Important**: The installer supports uploads up to 100GB by default. If you need different limits, edit the nginx configuration after installation.
+
+### Option 2: Manual Installation
+
+#### 1. VM Setup
+1. Create a new VM in VMware with the specifications above
+2. Install Ubuntu Server 22.04 LTS
+3. Update the system:
+   ```bash
+   sudo apt update && sudo apt upgrade -y
+   ```
+
+#### 2. Install Python and Dependencies
+```bash
+# Install Python 3.10+
+sudo apt install python3 python3-pip python3-venv -y
+
+# Create application directory
+sudo mkdir -p /opt/pdf-processor
+sudo chown $USER:$USER /opt/pdf-processor
+cd /opt/pdf-processor
+
+# Clone or copy the application files
+# (Assuming you have the files ready)
+
+# Create virtual environment
+python3 -m venv venv
+source venv/bin/activate
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+#### 3. Install Production Server (Gunicorn)
+```bash
+pip install gunicorn
+
+# Create systemd service
+sudo nano /etc/systemd/system/pdf-processor.service
+```
+
+Add the following content:
+```ini
+[Unit]
+Description=PDF Processor Web App
+After=network.target
+
+[Service]
+User=your-username
+Group=your-group
+WorkingDirectory=/opt/pdf-processor
+Environment="PATH=/opt/pdf-processor/venv/bin"
+ExecStart=/opt/pdf-processor/venv/bin/gunicorn -w 4 -b 0.0.0.0:8000 app:app
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```bash
+# Enable and start service
+sudo systemctl enable pdf-processor
+sudo systemctl start pdf-processor
+
+# Check status
+sudo systemctl status pdf-processor
+```
+
+### 4. Configure Nginx (Required for Production)
+
+**Important**: Nginx must be configured to handle large file uploads. The default nginx configuration limits uploads to 1MB, which will cause "413 Request Entity Too Large" errors.
+
+```bash
+sudo apt install nginx -y
+
+# Create nginx config with large file upload support
+sudo nano /etc/nginx/sites-available/pdf-processor
+```
+
+Add the following configuration (adjust `client_max_body_size` based on your needs):
+
+```nginx
+server {
+    listen 80;
+    server_name your-server-ip;
+
+    # Large file upload settings - CRITICAL for PDF processing
+    client_max_body_size 100G;        # Allow uploads up to 100GB
+    client_body_timeout 300s;         # 5 minute timeout for uploads
+    client_header_timeout 60s;        # Header timeout
+
+    # Security headers
+    add_header X-Frame-Options "SAMEORIGIN" always;
+    add_header X-XSS-Protection "1; mode=block" always;
+    add_header X-Content-Type-Options "nosniff" always;
+    add_header Referrer-Policy "no-referrer-when-downgrade" always;
+    add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;
+
+    location / {
+        proxy_pass http://127.0.0.1:5000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+
+        # Timeout settings for long-running PDF processing
+        proxy_connect_timeout 300s;
+        proxy_send_timeout 300s;
+        proxy_read_timeout 300s;
+
+        # Disable buffering for large uploads
+        proxy_buffering off;
+        proxy_request_buffering off;
+    }
+
+    # Static files
+    location /static/ {
+        alias /path/to/your/app/static/;
+        expires 1y;
+        add_header Cache-Control "public, immutable";
+    }
+}
+```
+
+```bash
+# Enable the site
+sudo ln -s /etc/nginx/sites-available/pdf-processor /etc/nginx/sites-enabled/
+sudo rm -f /etc/nginx/sites-enabled/default
+
+# Test configuration
+sudo nginx -t
+
+# Restart nginx
+sudo systemctl restart nginx
+```
+
+### 5. Access the Application
+- **With automated installer**: The installer will provide the exact URL and setup next steps
+- **Manual installation**: Open your web browser and navigate to `http://your-vm-ip` (nginx on port 80)
+- **Direct access**: `http://your-vm-ip:5000` (Flask development server)
+
+## Troubleshooting
+
+### Common Issues
+
+1. **413 Request Entity Too Large**: 
+   - **Cause**: Nginx upload limit is too small (default is 1MB)
+   - **Solution**: Ensure `client_max_body_size` is set to at least 100G in nginx config
+   - **Check**: `sudo nginx -t && sudo systemctl restart nginx`
+
+2. **Permission Denied on Static Files**:
+   - **Cause**: Nginx can't access logo/images in static directory
+   - **Solution**: Run the automated installer or manually set permissions:
+     ```bash
+     sudo usermod -a -G www-data $USER
+     sudo chmod -R 755 ~/pdf-sort-merge/static/
+     find ~/pdf-sort-merge/static/ -type f -exec sudo chmod 644 {} \;
+     sudo systemctl restart nginx
+     ```
+
+3. **Processing Stuck**: 
+   - **Check logs**: `sudo journalctl -u pdf-sort-merge -f` (automated install)
+   - **Check logs**: `sudo journalctl -u pdf-processor -f` (manual install)
+
+4. **Memory Issues**: Monitor with `htop` and increase RAM if needed
+
+5. **Slow Processing**: Ensure all CPU cores are being utilized
+
+### Installation Issues
+
+- **Automated installer fails**: Check that you're running as a regular user (not root) with sudo privileges
+- **Azure AD setup incomplete**: Follow [AZURE_AD_SETUP.md](AZURE_AD_SETUP.md) carefully
+- **PyMuPDF installation fails**: The app will still work but PDF processing will be disabled
+
+### Monitoring and Management
+
+```bash
+# Check CPU usage during processing
+htop
+
+# Monitor application logs (automated install)
+sudo journalctl -u pdf-sort-merge -f
+
+# Monitor application logs (manual install)
+sudo journalctl -u pdf-processor -f
+
+# Check disk I/O
+iotop
+
+# Service management (automated install)
+~/pdf-sort-merge/manage.sh status
+~/pdf-sort-merge/manage.sh logs
+~/pdf-sort-merge/manage.sh restart
+~/pdf-sort-merge/manage.sh update  # Pull latest code and restart
+```
+
+## Security Considerations
+- Run behind a reverse proxy (Nginx) in production
+- Use HTTPS with SSL certificates
+- Restrict access with firewall rules
+- Regularly update dependencies
+- Monitor for resource usage
+
+## Support
+For issues or questions, check the application logs and ensure your VM meets the minimum requirements.
