+Network Server Performance Benchmarking Toolbench
+=================================================
+
+This is a simple collection of scripts intended to benchmark the basic
+network performance of a variety of server frameworks.
+
+The servers are run inside a Docker container for environment stability,
+so to use this toolbench you need a reasonably recent Docker.
+
+Installation
+------------
+
+Install the following:
+
+- Docker
+- Python 3
+- Numpy
+
+Build the docker image containing the servers being tested by running
+``./build.sh``.
+
+The benchmarks can then be ran with ``./run_benchmarks``.  Use
+``./run_benchmarks --help`` for various options, including selective
+benchmark running.
