 -------------------
 Every type consists of required, optional and boolean parameters, which must
 be created in a newline seperated file in ***parameter/required***,
-***parameter/optional*** and ***parameter/boolean***. If either is missing,
+***parameter/required_multiple***, ***parameter/optional***, 
-the type will have no required, no optional, no boolean or no parameters at
+***parameter/optional_multiple*** and ***parameter/boolean***.
-all.
+Parameters which are allowed multiple times should be listed in
+required_multiple or optional_multiple respectively. For all other parameters
+the standard unix behaviour of the last given wins is applied.
+If either is missing, the type will have no required, no optional, no boolean
+or no parameters at all.
