-### Testing
-
-Changes can be tested by using [Packer](https://www.packer.io/) and
-[vmm(4)](https://man.openbsd.org/vmm.4) :
-
-*   This process depends on the [Go](https://golang.org/) programming language.
-
-**Packages**
-
-Needing a Golang eco system and some basics
-
-````
-pkg_add go-- packer-- git--
-````
-
-*   We use the [packer-builder-openbsd-vmm](https://github.com/double-p/packer-builder-openbsd-vmm) project to bridge Packer and vmm(4)
-
-````
-git clone https://github.com/double-p/packer-builder-openbsd-vmm.git
-````
-
-**builds**
-
-Set ````GOPATH```` (default: ~/go), if the 1.4GB dependencies wont fit.
-
-````
-make
-make install
-````
-
-*   You need your unprivileged user to be able to run vmctl(8) through doas(1)
-
-```
-echo "permit nopass myunprivilegeduser as root cmd /usr/sbin/vmctl" >> /etc/doas.conf
-```
-
-See packer-builder-openbsd-vmm/examples/README.examples for further instructions
-
-*   Enable NAT on your host machine
-
-```
-pass out on em0 inet from tap0:network to any nat-to (em0)
-```
-*assuming em0 is your egress interface*
