+## 🎓 What This Documentation Covers
+
+### Feature Summary
+
+Enables creation of **Zora Content Coins** on **Base chain** with:
+- ✅ Image uploads (JPEG, PNG, GIF, WebP, SVG)
+- ✅ Video uploads (MP4, WebM, MOV, M4V)
+- ✅ IPFS metadata storage via Zora
+- ✅ Backing by Gnars Creator Coin
+- ✅ Referral rewards to Gnars DAO treasury
+- ✅ Direct contract calls (no SDK abstraction)
+- ✅ Production-ready implementation
+
+### Implementation Details
+
+**New Files (7):**
+1. `src/app/create-coin/page.tsx` - UI form & success screen
+2. `src/hooks/useCreateCoin.ts` - Core deployment logic
+3. `src/lib/zora/factoryAbi.ts` - Contract ABI
+4. `src/lib/zora/poolConfig.ts` - Pool config encoder
+5. `src/app/api/coins/create/route.ts` - API endpoint
+6. `scripts/deploy-gnars-content-coin.ts` - CLI deployment
+7. `public/Zorb.png` - Branding asset
+
+**Modified Files (3):**
+1. `src/lib/config.ts` - Added Zora constants
+2. `src/components/layout/DaoHeader.tsx` - Added navigation
+3. `package.json` - Added `@zoralabs/coins-sdk`
+
+**Total Changes:** ~1,267 lines added

+
+## 💡 The Key Insight
+
+**Videos work exactly like images!**
+
+```typescript
+// This SAME method works for both:
+builder.withImage(imageFile);  // ✅ Images
+builder.withImage(videoFile);  // ✅ Videos too!
+```
+
+The Zora SDK automatically:
+- Detects file type
+- Uploads to IPFS
+- Creates metadata
+- Sets proper fields (image + animation_url for videos)
+
+**No separate video handling needed!** This is the magic that makes this implementation so elegant.
