├── models/                # AI models
│   └── Qwen3-1.7B-Q6_K.gguf
├── chat_history/          # Encrypted chat logs
├── identities/            # User identities
└── ipfs/                  # IPFS repository (if using embedded node)
```

---

## Updating

### Manual Update
1. Download new AppImage
2. Replace old AppImage
3. Run new version

### Automatic Updates

- AppImageUpdate integration planned

---

## Troubleshooting

### AppImage Won't Run

**Problem:** Permission denied  
**Solution:**
```bash
chmod +x VectorChat-*.AppImage
```

**Problem:** FUSE not available  
**Solution:**
```bash
# Extract and run
./VectorChat-*.AppImage --appimage-extract
./squashfs-root/AppRun
```

**Problem:** Missing libraries  
**Solution:** AppImage should be self-contained, but if issues persist:
```bash
# Install GTK3
sudo dnf install gtk3  # Fedora/Nobara
sudo apt install libgtk-3-0  # Ubuntu/Debian
```

### IPFS Node Issues

**Problem:** IPFS not found  
**Solution:** Install IPFS separately (see main docs)

**Problem:** Port conflicts  
**Solution:** VectorChat will auto-detect available ports
