+# Compatibility: ferro-ta vs TA-Lib
+
+See the full migration guide at [docs/migration_talib.rst](../migration_talib.rst).
+
+ferro-ta is designed as a **drop-in replacement** for TA-Lib (`talib` Python package) for the most commonly used indicators.
+
+## Quick Reference
+
+```python
+# TA-Lib
+import talib
+result = talib.SMA(close, timeperiod=14)
+
+# ferro-ta (identical API)
+import ferro_ta
+result = ferro_ta.SMA(close, timeperiod=14)
+```
+
+Full migration guide including all indicator mappings, known differences, and step-by-step migration: [migration_talib.rst](../migration_talib.rst)
+
+## Running Cross-Library Tests
+
+```bash
+# Requires TA-Lib C library + talib Python package
+pip install TA-Lib
+pytest tests/integration/test_vs_talib.py -v
+```
