## System Requirements

### Minimum Requirements

- **OS**: Linux, macOS, Windows (64-bit)
- **RAM**: 50MB
- **Disk**: 20MB
- **Network**: IPv6 support (enabled by default on most systems)

### Network Requirements

- Internet connection
- IPv6 capable network stack (standard on modern systems)
- No special firewall configuration needed (works with NAT)

## Troubleshooting

### "Command not found" Error

If you get a "command not found" error:

**Linux/macOS:**
- Ensure `/usr/local/bin` is in your PATH
- Try running with full path: `/usr/local/bin/mycelium`
- Check file permissions: `ls -l /usr/local/bin/mycelium`

**Windows:**
- Verify the installation directory is in your PATH
- Open a new Command Prompt after installation
- Try full path: `"C:\Program Files\Mycelium\mycelium.exe"`

### Permission Denied

If you get permission errors when running:

**Linux/macOS:**
```bash
# Make the binary executable
chmod +x /usr/local/bin/mycelium

# Run with sudo if needed for network operations
sudo mycelium --peers tcp://188.40.132.242:9651
```

**Windows:**
- Run Command Prompt as Administrator
- Check Windows Firewall settings

### IPv6 Not Available

Mycelium requires IPv6. If you get IPv6 errors:

**Linux:**
```bash
# Check if IPv6 is enabled
cat /proc/sys/net/ipv6/conf/all/disable_ipv6

# Enable if needed (0 = enabled)
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0
```

**macOS:**
IPv6 is enabled by default. Check System Preferences > Network.

**Windows:**
IPv6 is enabled by default. Check Network Adapter properties.
