-## Testing
 
-Testing is done with `kitchen-salt<https://github.com/simonmcc/kitchen-salt>`_ which means you'll also need Ruby.  Hopefully you're already using rbenv or whatever all of the cool kids are using these days, I'm a fuddy-duddy and use rbenv.  This formula has been tested on both 1.9.3 and 2.2.2 versions of Ruby.
 
-You should have `bundler` installed and have `bundle` on your $PATH, running this will set things up for Ruby.  If you're not running ruby-2.2.2 an exception will be thrown because the `Gemfile` is pinned to 2.2.2, update your Ruby version and re-run bundle command(s)

+Testing is done with KitchenSalt_ which means you'll also need a working Ruby setup and preferably 2.2.2, but you can use whatever version as long as you update the `Gemfile`.  You will also need `bundler` installed and can be done so with `gem install bundler`.
 
-\\ or
+If all that works, you should be able to run `kitchen test` which is an alias for `kitchen converge` + `kitchen verify` but it deletes the box on completion so it isn't very useful during development.  
 
-bundle install
-```
+.. _KitchenSalt: https://github.com/simonmcc/kitchen-salt
 
-Once you have successfully bundled things up, you should have the `kitchen` command on your $PATH. The first part is to run `kitchen converge` which will setup the environment by
- - creating a vagrant box
- - install salt
- - run the states defined in **golang-formula/.kitchen.yml**
-   
+Cheat Sheet
+------------
+
+.. code-block::
 
-Once you've successfully `converged` the environment, the tests can be executed. If you were to run `kitchen verify` the tests found in `golang-formula/test/integration/default`. Currently there are only tests which use the `bats<https://blog.engineyard.com/2014/bats-test-command-line-tools>`_ ` `Busser<https://github.com/test-kitchen/busser>`_. 
+   # Initial setup
+   which bundle || gem install bundler
+   bundle install
+   
+   # build vagrant box and run states
+   kitchen converge
+   
+   # run tests in `test/integration/default`
+   kitchen verify
 
-You can also run the `kitchen test` command, but that will destroy the existing vagrant before converging, roughly:
-```
-kitchen destroy && kitchen converge && kitchen verify && kitchen destroy
-```
-which is useful for CI pipelines but not so much during dev.
+   # sledgehammer
+   kitchen destroy
 
+   # alias for running  (destroy + converge + verify + destroy)
+   kitchen test
