-This program .
+# advanced_area.py — Fast Area of Triangle
+
+This is a faster, flexible alternative to `area.py` that keeps the original script intact while adding **CLI**, **batch**, and **auto-vectorized** modes (NumPy if available).
+
+## Why this exists
+- Keep `area.py` unchanged for tutorials and simple users.
+- Provide a high-throughput path for large inputs (stdin / files).
+- Offer a clean CLI for scripting and CI.
+
+## Quick start
+```bash
+# Interactive prompts
+python advanced_area.py
+
+# One-off CLI
+python advanced_area.py 3 4
+# -> 6
+
+# Batch via stdin (one area per line in output)
+printf "3 4\n5 2\n8 7\n" | python advanced_area.py
+# -> 6
+# -> 5
+# -> 28
