+### Pre-Setup Vagrant Pseudo Cluster
+One can see the interactions of a three server Ratis cluster with a load-generator running against it by using the `run_all_tests.sh` script found in [dev-support/vagrant/]. See the [dev-support/vagrant/README.md] for more on dependencies and what is setup. This will allow one to try a fully setup three server Ratis cluster on a single VM image, preventing resource contention with your development host and allowing failure injection too.

+# What is this?
+
+This is a series of scripts for [Vagrant](https://vagrantup.com) to stand-up and test [Apache (Incubating) Ratis](https://ratis.incubator.apache.org/) servers and clients. One needs to have Vagrant and [VirtualBox](https://virtualbox.org) installed to stand-up these tests environments.
+
+# What is provided?
+
+This provides a multi-host `Vagrantfile` which provides the following described VM's:
+
+## `ratis-build` VM
+This provides a built version of Ratis with the [Namazu](https://github.com/osrg/namazu) test framework as well
+
+## `ratis-servers` VM
+This leverages the built Ratis servers to run a three server cluster and load generator. The Ratis servers are listening on ports 6000, 6001, 6002. The four processes are started and daemonized using [GNU Screen](https://www.gnu.org/software/screen/). The daemons further log to files in the home directory of the test user.
+
+## `ratis-hdd-slowdown` VM
+This VM starts the three Ratis servers and load genearator as the `ratis-servers` VM. However, the three servers contend with their storage directories made pathological (slow and error-prone) by Namazu. The configuration of pathology in namazu can be tuned in [hdd_config.toml](./namazu_configs/hdd_config.toml).
+
+The test VM's can be stoped and all daemons restarted via: `vagrant up --provision <VM name>`
+One can login to the VM and read the message-of-the-day for instructions on how to read the daemon logs; or connect to the Screen session.
+
+# How to get started:
+There is a shell script `run_all_tests.sh` which provides a single entrypoint for building or cleaning up all tests.
+To visualize the flow of building all tests, a BPMN diagram of the intended process flow is: ![Vagrantfile BPMN Flow][Vagrantfile_BPMN]
+
+Execute `run_all_tests.sh` with option `build`:
+* Builds the `ratis-build` VM
+* Packages a [Vagrant box](https://www.vagrantup.com/docs/boxes.html) to build test VMs off of
+* Builds all test VMs and suspends them on success
+
+Execute `run_all_tests.sh` with option `clean`:
+* Destroys all test VMs
+* Destroys the `ratis-build` VM
+* Removes the `ratis-test` from Vagrant
+* Removes the `ratistest.box` from the local file-system
+
+Run the tests for a machine with `vagrant resume`:
+* e.g. `vagrant resume ratis-servers && vagrant ssh ratis-servers`
