Each how-to is a single ordered procedure with no conceptual detours. If a guide references a concept you do not know, follow the link to the Explanation page that owns it.

## Available guides

- [Add a firewall rule](/docs/plain-vms/how-to/add-a-firewall-rule) — open or close inbound TCP / UDP ports on the per-VM Cloud Firewall.
- [Attach an SSH key from the Vault](/docs/plain-vms/how-to/attach-an-ssh-key-from-the-vault) — wire a stored public key to a new VM.

If a guide you need is missing, file an issue — we add guides as users hit the same job twice.
