+# Test for Network Benchmark Tool
+
+[This script](./test.sh) verifies the network benchmarks in the [kubernetes/perf-tests](https://github.com/kubernetes/perf-tests) package. It clones the specified fork and branch, runs network benchmark tests against a provided image, and cleans up after execution.
+
+## Usage
+
+Set environment variables as needed:
+• FORK_TO_TEST (default: kubernetes/perf-tests)
+• BRANCH_TO_TEST (default: master)
+• IMAGE_TO_TEST (default: ghcr.io/ritwikranjan/nptest:latest)
+• KUBECONFIG (default: ~/.kube/config)
+
+```shell
+bash test.sh
+```
