 simple tests against it after applying the module. You can run this
 with:
 
-    bundle exec rake acceptance
+```sh
+bundle exec rake acceptance
+```
 
 This will run the tests on the module's default nodeset. You can override the
 nodeset used, e.g.,
 
-    BEAKER_set=centos-7-x64 bundle exec rake acceptance
+```sh
+BEAKER_set=centos-7-x64 bundle exec rake acceptance
+```
 
 There are default rake tasks for the various acceptance test modules, e.g.,
 
-    bundle exec rake beaker:centos-7-x64
-    bundle exec rake beaker:ssh:centos-7-x64
+```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:
+
+```
+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:
 
-    docker exec -it -u root ${container_id_or_name} bash
+```sh
+docker exec -it -u root ${container_id_or_name} bash
