 # AI-workflows
 
 A collections of portable, real-world AI workflows for testing and benchmarking
+
+## Using Vagrant
+
+The included Vagrantfile can be used to build the examples if your system does
+not support singularity or if you would prefer not to install singularity on
+your host. The Vagrantfile has support for the VirtualBox and libvirt providers.
+
+To create the virtual machine run
+
+```bash
+vagrant up --provider <provider>
+```
+
+for example
+
+```bash
+vagrant up --provider libvirt
+```
+
+When this is finished, you can connect to the virtualmachine in the normal way
+
+```bash
+vagrant ssh
+```
+
+and will find this project mounted at `/vagrant/`
