-Internal documentation for admins!
+This section is for HPCCF admins to document our internal infrastructure, processes, and
+architectures.
+Although the information may be of _interest_ to end users, it is not designed or maintained for
+their consumption; nothing written here should be confused as an offering of service.
+For example, although we describe our [Virtual Machine](vms.md) infrastructure, which we used for
+hosting a variety of production-essential services for our clusters, we do **not** offer VM hosting
+for end users.
