+# Web Tooling Benchmark
+
+This is a clone/fork of the original [Web Tooling Benchmark](https://github.com/v8/web-tooling-benchmark).
+Unlike the original, this is a JetStream-oriented version.
+
+This benchmark provides workloads for common web tools.
+
+
+## Build Instructions
+
+```bash
+# install required node packages.
+npm ci
+# build the workload, output is ./dist
+npm run build
+```
