+The [`bench-node-cli`](https://github.com/RafaelGSS/bench-node-cli) tool allows you to execute a `bench-node` benchmark
+from any location, eliminating the need to install the `bench-node` package locally.
+Simply use the following command to run your benchmark:
+
+```bash
+npx bench-node-cli my-benchmark.js
+```
 See the [examples folder](./examples/) for more common usage examples.
