+  * The (paid) VMware plugin requires a licensed copy of VMware Workstation/Fusion
+* [Docker](https://www.docker.com/)
 
-Other than having Vagrant and Virtualbox installed and possibly a restart of your computer afterwards, you can simple run a 'vagrant up' anywhere inside the folder where you checked out this project and it will start a Linux virtual machine that contains all the tools required to build this project. There is a post Vagrant startup hint that will get you off on the right foot, otherwise you can also reference the build documentation below.

+Certain versions of Virtualbox 5 appear to have an incompatibility with the Virtualbox extensions installed in the boxes in this Vagrantfile. If you encounter any issues with the /vagrant mount not succeeding, please upgrade your version of Virtualbox to at least 5.0.12. **Alternately, you can try running the following command:**

+
+### How do I remove an existing environment?
+Finished with your environment? From anywhere inside the folder where you checked out this project, Execute:
+
+```console
+vagrant destory
+```
+
+### What if I want to use Docker directly?
+Want to benefit from the Vagrant workflow without a virtual machine? The Vagrantfile is configured to bypass running a virtual machine, and run the container directly. Execute the following when bringing up the environment to force the use of Docker:
+```console
+vagrant up --provider=docker
+```
+
+### How do I access the virtual machine instead of the Docker container?
+Execute the following to bypass the `vagrant` user booting directly to the official qmk builder image:
+
+```console
+vagrant ssh -c 'sudo -i'
+```
