+# Nomad Bench
+
+The Nomad Bench project provides reusable infrastructure automation to run test scenarios in order
+to collect metrics and data from Nomad clusters running at scale. The core goal of the project is
+to achieve reproducible large scale test scenarios so we can better understand how Nomad scales
+and uncover problems that are only detected in large cluster deployments. It is also used to
+perform release soak testing, among other things.
+
+The [repository][bench-repo] contains all the infrastructure and details to get started with your
+own load testing.
