+### Vagrant
+
+You may want to kickstart your k3s cluster by using Vagrant to quickly build you all needed VMs with one command.
+Head to the `vagrant` subfolder and type `vagrant up` to get your environment setup.
+After the VMs have got build, deploy k3s using the Ansible playbook `site.yml` by the
+`vagrant provision --provision-with ansible` command.
+
 ## Thanks 🤝
 This repo is really standing on the shoulders of giants.  To all those who have contributed.
