Minimal hardware requirements for newcomers

[corticalstack]

As relative newbie to kubernetes, homelabbing etc, when first provisioning a collection of VMs, I configured disks with 4GB. task ansible:install failed against remote /tmp as the VM disk was 100%. Increased disk to 8GB, and after ansible:install completing successfully, checked VM disk space with df -h. 51% utilised. Just a thought. Thanks for all this amazing work, opening my eyes for possibilities!
