 ### Requirements
 
-- [VirtualBox 7.x](https://www.virtualbox.org/wiki/Downloads)
+Install all three **before** the workshop (ideally the day before — downloads are large):
-- [Vagrant 2.4.x](https://developer.hashicorp.com/vagrant/downloads)
+
-- Git
+| Tool               | Install                                                          |
-- 12 GB RAM free on your laptop, ~15 GB disk

+```bash
+VBoxManage --version && vagrant --version && git --version
+```

 ```bash
-git clone https://github.com/innspire/ops-demo.git
+git clone https://github.com/paulharkink/ops-demo.git
 cd ops-demo
