-How to debug in VMs
+## Debugging in VMs
+
+Most tests run inside VMs powered by [AnyVM.org](https://github.com/anyvm-org).
+
+Start a FreeBSD VM locally with one command:
+```bash
+python3 anyvm.py --os freebsd
+```
+
+Then debug your test code inside the VM. For more options, see the [AnyVM.org docs](https://github.com/anyvm-org).
