+
+## 🎯 Quick Decision Guide
+
+### Choose **OPNsense** if you want:
+- ✅ Application-level control (block TikTok, allow Khan Academy)
+- ✅ Deep Packet Inspection (see WHAT apps are being used)
+- ✅ Professional parental controls (Zenarmor)
+- ✅ Enterprise-grade reporting
+- ✅ Time quotas per application
+- ✅ Content filtering that can't be bypassed
+- **Cost: $400-450 hardware + $59/year Zenarmor**
+
+### Choose **OpenWRT** if you want:
+- ✅ Zero cost solution
+- ✅ Basic bandwidth monitoring
+- ✅ MAC-based blocking (all or nothing)
+- ✅ Learning experience
+- **Cost: $0 (use existing Archer AX72 Pro)**
+
+## 💡 Recommendation for Your Setup
+
+Given you have **3 children (ages 14, 15, 17)** with **22 devices**, you need:
+1. **Granular control** - different rules per age group
+2. **Application visibility** - know what they're doing
+3. **Professional reporting** - daily usage summaries
+4. **Content filtering** - age-appropriate restrictions
+5. **Room to grow** - adjust as kids mature
+
+**RECOMMENDED:** OPNsense on Protectli VP2420 ($400) + Zenarmor Home ($59/year)
+
+This gives you the same capabilities as $500/year commercial parental control services, PLUS professional firewall and network security.
+
+## 📖 Files Available for Download

+
+## 🚀 Next Steps
+
+1. **Read OPNSENSE_VS_OPENWRT_COMPARISON.md** (the most important doc!)
+2. **Decide:** OPNsense ($400) vs OpenWRT ($0)
+3. **If OPNsense:** Order Protectli VP2420
+4. **If OpenWRT:** Flash firmware on Archer AX72 Pro
+5. **Follow implementation guide** for your chosen path
