 .Ss Procedures
+Rule procedure is defined as a collection of extension calls (it may have
+none).
+Every extension call has a name and a list of options in a form of
+key-value pairs.
+Depending on the call, key might represent the argument and the value
+might be optional.
+For example:
+.Bd -literal
+procedure "someproc" {
+       log: npflog0
+       normalise: "random-id", "min-ttl" 64
+}
+.Ed
+.Pp
+In this case, procedure has a call to logging and normalisation modules.
