@@ -209,14 +209,18 @@ Note the following about the testing process:
 - Testing is done publicly and all results are shared.
 
 Τhe following table details the testing done against the reference architectures along with the frequency and results.
-Testing is continuously evaluated and iterated on, so the table is constantly updated.

+1. The list above is non exhaustive. Additional testing is continuously evaluated and iterated on, and the table is updated regularly.
+1. The Omnibus reference architectures are VM-based only and testing has shown that they perform similarly on equivalently specced hardware regardless of Cloud Provider or if run on premises.
