### Manual WiFi Setup

For new networks or when automatic retrieval fails:

1. Enter SSID (network name)
2. Select security type (WPA/WPA2, WEP, Open)
3. Enter password if required

Generated QR codes work with all modern smartphones!

## 📁 File Upload & Sharing

BBQR integrates with 0x0.st for easy file sharing:

### How It Works

2. Generate QR code containing download information
3. Scan QR code to download and reassemble file
4. Automatic integrity verification

## 🔍 QR Code Reading

BBQR can decode various QR code types:

### WiFi QR Codes

- Displays network name, security type, password
- Can automatically connect on Windows
- Supports standard WiFi QR format

### File Upload QR Codes

- Shows file info (name, size, chunks)

## 👀 File Watching

Monitor files for changes and auto-generate QR codes:

```bash
# Watch file with default output
python bbqr.py --watch notes.txt

# Custom output location
python bbqr.py --watch journal.md --output qr_codes/journal_qr.png

# Custom QR size
python bbqr.py --watch data.txt --size 15
```

Uses cross-platform file watching (falls back to polling if needed).

## 📂 Multi QR Generation

Generate QR codes from multiple lines in a file:

```bash
python bbqr.py --multi urls.txt
python bbqr.py --multi contact_list.txt --size 12
```

Creates numbered QR code files in a `qrcodes/` directory.
