+# `cascade`
+
+The next iteration of the cascade network.
+
+Should it have been thunder?
+
+Probably.
+
+It's cascade anyway.
+
+## Usage
+
+From a [Proxmox VE][PVE] machine with [Nix][NIX] installed:
+
+```bash
+nix-shell
+```
+
+Guidance will be printed which should be followed.
+
+## Prerequisites
+
+In order to discover your network and configure hosts, this configuration management system requires the following:
+* Samba DC with functioning DNS and DHCP server.
+* You must be able to auth with Kerberos to Samba.
+* Proxmox running on the local host
+* Proxmox should have a local filesystem called hdd-fs
+
+
+NIX: https://www.nixos.org
