+## 🚀 Crypto Quick-Start
+
+Enable crypto trading by setting the `ASSET_CLASS` environment variable:
+
+```bash
+ASSET_CLASS=CRYPTO python src/main.py --pair BTC/USDT --exchange binance
+```
+
+Set `ALLOW_MARGIN=1` to enable margin trading.
+
+### Environment Variables
+
+| Variable | Description | Default |
+|---|---|---|
+| `ASSET_CLASS` | `EQUITY` or `CRYPTO` | `EQUITY` |
+| `ALLOW_MARGIN` | Enable shorting/margin when set to `1` | `0` |
+
 4. Set your API keys:

+# 0002 - Enable Crypto Asset Class
+
+## Context
+
+The platform originally supported only equity trading using daily OHLCV data. Expanding to spot crypto pairs requires new data sources, risk constraints, and agent logic.
+
+## Decision
+
+Introduce a feature flag `ASSET_CLASS` defaulting to `EQUITY`. When set to `CRYPTO`, the system routes price data through CCXT, adds crypto specific analysts, and adjusts risk management.
+
+## Consequences
+
+- Maintains backward compatibility with equity workflows.
+- Adds dependencies on `ccxt` and `pycoingecko`.
+- CI runs test suites for both asset classes.
