+# Primary Disk Layout
+
+A module for the "disk-layout" category MUST be choosen.
+
+There is exactly one slot for this type of module in the UI, if you don't fill the slot, your machine cannot boot
+
+This module is a good choice for most machines. In the future clan will offer a broader choice of disk-layouts
+
+The UI will ask for the options of this module:
+
+`device: "/dev/null"`
+
+# Usage example
+
+`inventory.json`
+```json
