# 🎯 START HERE

Welcome to **onvif-go** - A comprehensive Go library and CLI tool for ONVIF camera discovery and control.

## ⚡ Quick Start (2 minutes)

### 1. Try the Interactive CLI
```bash
cd /workspaces/go-onvif
./cmd/onvif-cli/onvif-cli
```
You'll see the main menu. Press `1` to discover cameras on your network.

### 2. Try Non-Interactive Mode
```bash
# Discover cameras on a specific interface
./onvif-cli discover -interface eth0 -timeout 5

# Or using old syntax
./onvif-cli -op discover -interface eth0
```

### 3. Try the Quick Tool
```bash
./cmd/onvif-quick/onvif-quick discover -interface eth0
```
