+# WooNooW
+
+**WooNooW** is a modern experience layer for WooCommerce — enhancing UX, speed, and reliability **without data migration**.  
+It keeps WooCommerce as the core engine while providing a modern React-powered interface for both the **storefront** (cart, checkout, my‑account) and the **admin** (orders, dashboard).
+
+---
+
+## 🔍 Background
+
+WooCommerce is the most used e‑commerce engine in the world, but its architecture has become heavy and fragmented.  
+With React‑based blocks (Checkout, Cart, Product Edit) and HPOS now rolling out, many existing addons are becoming obsolete or unstable.  
+WooNooW bridges the gap between Woo’s legacy PHP system and the new modern stack — so users get performance and simplicity without losing compatibility.
+
+---
+
+## 🚀 Key Principles
+
+- **No Migration Needed** – Woo data stays intact.  
+- **Safe Activate/Deactivate** – revert to native Woo anytime, no data loss.  
+- **Hybrid by Default** – SSR + React islands for Cart/Checkout/My‑Account.  
+- **Full SPA Toggle** – optional React‑only mode for max performance.  
+- **HPOS Mandatory** – optimized datastore and async operations.  
+- **Compat Layer** – hook mirror + slot rendering for legacy addons.  
+- **Async Mail & Tasks** – powered by Action Scheduler.
+
+---
+
+## 🧱 Tech Stack
+
+| Layer | Technology |
+|--------|-------------|
+| Backend | PHP 8.2+, WordPress, WooCommerce (HPOS), Action Scheduler |
+| Frontend | React 18 + TypeScript, Vite, React Query, Tailwind (optional) |
+| Build & Package | Composer, NPM, ESM scripts, Zip automation |
+| Architecture | Modular PSR‑4 classes, REST‑driven SPA islands |
