 Salt Engine for Virtual Node Management
 
 This engine manages the automated provisioning of virtual machines in Security Onion's
-virtualization infrastructure. It processes VM configurations from a nodes file and handles
+virtualization infrastructure. It processes VM configurations from a VMs file and handles
 the entire provisioning process including hardware allocation, state tracking, and file ownership.
