+
+## 🔄 Detailed Process
+
+### 1. Development Phase
+- Developer membuat perubahan di branch `main`
+- Test lokal menggunakan `pnpm dev`
+- Commit dan push perubahan ke repository
+
+### 2. Deployment Phase
+- Jalankan script deploy manual: `./scripts/deploy-manual.sh`
+- Script akan:
+  - Pull latest changes dari main
+  - Install dependencies dengan pnpm
+  - Build project dengan Astro
+  - Switch ke branch gh-pages
+  - Copy built files ke root
+  - Commit dan push ke gh-pages branch
+
+### 3. GitHub Pages Deployment
+- GitHub Pages otomatis detect perubahan di branch gh-pages
+- Website di-deploy ke https://www.konxc.space
+- Proses ini membutuhkan waktu 2-5 menit
+
+## 🎯 Key Benefits
+
+1. **No Billing Issues**: Tidak menggunakan GitHub Actions
+2. **Manual Control**: Developer memiliki kontrol penuh atas deployment
+3. **Reliable**: Script yang sederhana dan dapat diandalkan
+4. **Cross-Platform**: Support Linux, macOS, dan Windows
+5. **Documentation**: Dokumentasi lengkap untuk tim
+
+## ⚠️ Important Notes
+
+- **Branch Separation**: Main untuk development, gh-pages untuk deployment
+- **Manual Process**: Deployment harus dilakukan secara manual
+- **Script Dependency**: Pastikan pnpm dan Node.js terinstall
+- **Timing**: GitHub Pages butuh waktu untuk update
+
+## 🛠️ Maintenance
+
+- Script dapat diupdate sesuai kebutuhan
+- Dokumentasi harus selalu up-to-date
+- Tim harus familiar dengan proses manual deployment
+- Backup penting dilakukan secara teratur
