 description: |
-  Evaluates a list of conditions and exposes variables as outputs.
-  Conditions are evaluated in order. All matching conditions are applied.
-  If multiple conditions set the same variable, the last matching value wins.
+  Evaluates a set of rules and exposes variables as outputs.
+
+  Rules are evaluated in the order they are defined.
+
+  A rule matches when any of its conditions match the supplied context.
