 This module has grown over time based on a range of contributions from
 people using it. If you follow these contributing guidelines your patch
 will likely make it into a release a little more quickly.
 
 ## Contributing
 
 Please note that this project is released with a Contributor Code of Conduct.
 By participating in this project you agree to abide by its terms.
 [Contributor Code of Conduct](https://voxpupuli.org/coc/).
 
 1. Fork the repo.
 
 1. Create a separate branch for your change.
 
 1. We only take pull requests with passing tests, and documentation. [travis-ci](http://travis-ci.org)
    runs the tests for us. You can also execute them locally. This is explained
    in a later section.
 
 1. Checkout [our docs](https://voxpupuli.org/docs/#reviewing-a-module-pr) we
    use to review a module and the [official styleguide](https://puppet.com/docs/puppet/6.0/style_guide.html).
    They provide some guidance for new code that might help you before you submit a pull request.
 
 1. Add a test for your change. Only refactoring and documentation
    changes require no new tests. If you are adding functionality
    or fixing a bug, please add a test.
 
 1. Squash your commits down into logical components. Make sure to rebase
    against our current master.
 
 1. Push the branch to your fork and submit a pull request.
 
 Please be prepared to repeat some of these steps as our contributors review
 your code.
 
 ## Dependencies
 
 The testing and development tools have a bunch of dependencies,
 all managed by [bundler](http://bundler.io/) according to the
 [Puppet support matrix](http://docs.puppetlabs.com/guides/platforms.html#ruby-versions).
 
 By default the tests use a baseline version of Puppet.
 
 If you have Ruby 2.x or want a specific version of Puppet,
 you must set an environment variable such as:
 
 ```sh
 export PUPPET_VERSION="~> 5.5.6"
 ```
 
 You can install all needed gems for spec tests into the modules directory by
 running:
 
 ```sh
-bundle install --path .vendor/ --without development system_tests release
+bundle install --path .vendor/ --without development system_tests release --jobs "$(nproc)"
 ```
 
 If you also want to run acceptance tests:
 
 ```sh
-bundle install --path .vendor/ --with system_tests --without development release
+bundle install --path .vendor/ --with system_tests --without development release --jobs "$(nproc)"
 ```
 
 Our all in one solution if you don't know if you need to install or update gems:
 
 ```sh
-bundle install --path .vendor/ --with system_tests --without development release; bundle update; bundle clean
+bundle install --path .vendor/ --with system_tests --without development release --jobs "$(nproc)"; bundle update; bundle clean
+```
+
+As an alternative to the `--jobs "$(nproc)` parameter, you can set an
+environment variable:
+
+```sh
+BUNDLE_JOBS="$(nproc)"
+```
+
+### Note for OS X users
+
+`nproc` isn't a valid command unter OS x. As an alternative, you can do:
+
+```sh
+--jobs "$(sysctl -n hw.ncpu)"
 ```
 
 ## Syntax and style
 
 The test suite will run [Puppet Lint](http://puppet-lint.com/) and
 [Puppet Syntax](https://github.com/gds-operations/puppet-syntax) to
 check various syntax and style things. You can run these locally with:
 
 ```sh
 bundle exec rake lint
 bundle exec rake validate
 ```
 
 It will also run some [Rubocop](http://batsov.com/rubocop/) tests
 against it. You can run those locally ahead of time with:
 
 ```sh
 bundle exec rake rubocop
 ```
 
 ## Running the unit tests
 
 The unit test suite covers most of the code, as mentioned above please
 add tests if you're adding new functionality. If you've not used
 [rspec-puppet](http://rspec-puppet.com/) before then feel free to ask
 about how best to test your new feature.
 
 To run the linter, the syntax checker and the unit tests:
 
 ```sh
 bundle exec rake test
 ```
 
 To run your all the unit tests
 
 ```sh
 bundle exec rake spec
 ```
 
 To run a specific spec test set the `SPEC` variable:
 
 ```sh
 bundle exec rake spec SPEC=spec/foo_spec.rb
 ```
 
 ### Unit tests in docker
 
 Some people don't want to run the dependencies locally or don't want to install
 ruby. We ship a Dockerfile that enables you to run all unit tests and linting.
 You only need to run:
 
 ```sh
 docker build .
 ```
 
 Please ensure that a docker daemon is running and that your user has the
 permission to talk to it. You can specify a remote docker host by setting the
 `DOCKER_HOST` environment variable. it will copy the content of the module into
 the docker image. So it will not work if a Gemfile.lock exists.
 
 ## Integration tests
 
 The unit tests just check the code runs, not that it does exactly what
 we want on a real machine. For that we're using
 [beaker](https://github.com/puppetlabs/beaker).
 
 This fires up a new virtual machine (using vagrant) and runs a series of
 simple tests against it after applying the module. You can run this
 with:
 
 ```sh
 bundle exec rake acceptance
 ```
 
 This will run the tests on the module's default nodeset. You can override the
 nodeset used, e.g.,
 
 ```sh
 BEAKER_set=centos-7-x64 bundle exec rake acceptance
 ```
 
 There are default rake tasks for the various acceptance test modules, e.g.,
 
 ```sh
 bundle exec rake beaker:centos-7-x64
 bundle exec rake beaker:ssh:centos-7-x64
 ```
 
 If you don't want to have to recreate the virtual machine every time you can
 use `BEAKER_destroy=no` and `BEAKER_provision=no`. On the first run you will at
 least need `BEAKER_provision` set to yes (the default). The Vagrantfile for the
 created virtual machines will be in `.vagrant/beaker_vagrant_files`.
 
 Beaker also supports docker containers. We also use that in our automated CI
 pipeline at [travis-ci](http://travis-ci.org). To use that instead of Vagrant:
 
-```
+```sh
 PUPPET_INSTALL_TYPE=agent BEAKER_IS_PE=no BEAKER_PUPPET_COLLECTION=puppet5 BEAKER_debug=true BEAKER_setfile=debian9-64{hypervisor=docker} BEAKER_destroy=yes bundle exec rake beaker
 ```
 
 You can replace the string `debian9` with any common operating system.
 The following strings are known to work:
 
 * ubuntu1604
 * ubuntu1804
 * debian8
 * debian9
 * centos6
 * centos7
 
 The easiest way to debug in a docker container is to open a shell:
 
 ```sh
 docker exec -it -u root ${container_id_or_name} bash
 ```
