## Usage Instructions

### Verify ISO Integrity

```bash
cd output/

# Verify SHA256 checksum
sha256sum -c knel-football-secure-v1.0.0.iso.sha256

# Verify MD5 checksum
md5sum -c knel-football-secure-v1.0.0.iso.md5

# Expected output:
# knel-football-secure-v1.0.0.iso: OK
```

### Create Bootable USB

```bash
# Identify USB device (e.g., /dev/sdX)
lsblk

# Write ISO to USB (WARNING: This will erase all data on USB)
sudo dd if=knel-football-secure-v1.0.0.iso of=/dev/sdX bs=4M status=progress sync

# Alternative using cat
sudo cat knel-football-secure-v1.0.0.iso > /dev/sdX
sync
```

### Test in Virtual Machine

```bash
# Using virt-install
virt-install \
  --name knel-football-test \
  --memory 2048 \
  --vcpus 2 \
  --cdrom output/knel-football-secure-v1.0.0.iso \
  --os-variant debian10 \
  --graphics spice \
  --disk size=20

# Boot the VM and test:
# 1. Encryption setup during installation
# 2. Passphrase prompt at boot
# 3. Login with strong password
# 4. VPN configuration
# 5. Security features
```

### Installation Notes

1. **Boot from USB/DVD**
2. **Follow automated installation prompts**
3. **Set encryption passphrase** (14+ chars, complexity required)
4. **System installs with full disk encryption**
5. **System reboots**
6. **Enter encryption passphrase at boot**
7. **Login with credentials**

### Security Reminders

⚠️ **CRITICAL**: Store your encryption passphrase securely!
- The passphrase is required at EVERY system boot
- There is NO backdoor or recovery method
- Losing the passphrase = permanent data loss
- Use a secure password manager
- Never write it down in plaintext

---

## Next Steps

1. **Test ISO in Virtual Machine**
   - Verify encryption setup works
   - Test passphrase prompt at boot
   - Verify password complexity enforcement
   - Test all security features

2. **Security Validation**
   - Run comprehensive security tests
   - Verify all requirements met
   - Document any issues or fixes

3. **Documentation**
   - Update user manual with encryption requirements
   - Create installation guide screenshots
   - Document troubleshooting steps

4. **Distribution Preparation**
   - Create release announcement
   - Sign ISO with GPG key
   - Prepare checksum verification page
   - Update download page

## Troubleshooting

### Common Issues

1. **USB Won't Boot**
   - Verify ISO integrity with checksums
   - Try different USB port
   - Check UEFI boot settings
   - Try legacy BIOS mode if UEFI fails

2. **Encryption Passphrase Not Accepted**
   - Ensure 14+ characters
   - Check complexity requirements (upper, lower, digit, special)
   - Avoid common words and patterns
   - Try different passphrase if needed

3. **Installation Fails**
   - Check system meets minimum requirements
   - Verify enough disk space (64 GB minimum)
   - Check hardware compatibility
   - Review installation log
