+* Explain the difference between a singleton and non-singleton type:
+
+A single type can only be used once per host. 
+
+(I don't see yet why this is important.)
+
+** Reference 
+   If a type is flagged as a singleton, it may be used only once per host. This is useful for types which can be used only once on a system. Singleton types do not take an object name as argument.

+* Explain the difference between the different verbosity levels
+
+Verbosity levels are used to change the amount of information that is output on stdout about the configuration run.

+
+# verbosity
+#     Set verbosity level. Valid values are:
