+# Benchmark Comparison Framework
+
+This directory contains a framework for comparing `bench-node` against other popular benchmark libraries:
+
+- [Benchmark.js](https://benchmarkjs.com/)
+- [Mitata](https://github.com/evanwashere/mitata)
+- [Tinybench](https://github.com/tinylibs/tinybench)
+
+## Test Cases
+
+The comparison focuses on four key test scenarios:
+
+1. **JIT Optimizable** - Simple operations that the JavaScript JIT compiler might optimize away
+2. **Regex Test** - Regular expression pattern matching operations
+3. **Fibonacci** - CPU-bound recursive calculation
+
+## Running the Comparisons
+
+To run any of the comparison scripts, use:
+
+```bash
+node --allow-natives-syntax examples/benchmark-comparison/comparison.js
+```
+
+> **Note:** All bench-node scripts must be run with the `--allow-natives-syntax` flag.
