+## ✨ About
+
+AlphaQuant is a modern, modular, full-stack **JavaScript framework for quant research and strategy development**. Built for **Node.js and browser**, it brings real quant tools to web-native developers.
+
+- 📊 Pandas-style DataFrame (via Danfo.js)
+- 🧠 TA indicators (RSI, EMA, SMA, MACD...)
+- 🎯 Strategy interface: `onBar(data)` / `class Strategy`
+- 📉 Backtester with equity, metrics, trades
+- 🖥 CLI & browser playground (coming)
+- 🌐 LLM-powered code generator (planned)
+
+---
+
+## 🛠 Getting Started
+
+```bash
+npm install @alphaquant/core @alphaquant/ta @alphaquant/backtest
+```
+
+```ts
+import { SMA, RSI } from '@alphaquant/ta';
+import { BacktestEngine } from '@alphaquant/backtest';
+
+const result = BacktestEngine.run(myStrategy, data);
+console.log(result.metrics);
+```
+
+Full example: [`examples/sma-cross.ts`](./examples/sma-cross.ts)
+

+
+## 🧪 Development Workflow
+
+```bash
+turbo run lint    # Lint all packages
+turbo run build   # Compile everything
+turbo run test    # Run tests (WIP)
+npx changeset     # Start new release
+```
+
+🔁 CI/CD is fully automated via GitHub Actions + Changesets. See [How CI/CD Works](#️how-cicd-works)
+
+---
+
+## 💼 Roadmap Highlights
+
+- [x] Strategy + backtesting engine
+- [x] CLI interface (Node.js)
+- [ ] Portfolio optimization
+- [ ] Time-series ARIMA/GARCH
+- [ ] QuantLib WASM pricing
+- [ ] Web-based UI & visual builder
+- [ ] GPT-style code assistant
+
+---
+
+## 🛠️ How CI/CD Works
+
+AlphaQuant uses **Turborepo + Changesets + GitHub Actions** to provide zero-config continuous integration and delivery.
+
+- ✅ ESLint via `.eslintrc.json` (strict style rules)
+- ✅ Commitlint + Husky enforce Conventional Commits
+- ✅ `turbo run` manages build/test/lint pipelines
+- 🚀 `changeset` auto-generates versions + changelog
+- 📦 Auto-publish to npm on merge to `main` (with `NPM_TOKEN`)
