./dvmcfg wizard
```
The wizard guides you step-by-step through configuration creation with prompts and validation.

### Create New Configuration (CLI)
```bash
./dvmcfg create --template hotspot --output /etc/dvm/config.yml
```

### Create Trunked System
```bash
./dvmcfg trunk create --cc-port 62031 --vc-count 2 --base-dir /etc/dvm/trunked
```

### Validate Configuration
```bash
./dvmcfg validate /etc/dvm/config.yml
```

## Templates

- **repeater**: Standalone repeater
- **control-channel**: Dedicated control channel for trunking
- **voice-channel**: Voice channel for trunking
