-Put each info parameter on a separate line.
+Put each info parameter on a separate line. The syntax is almost identical to [[jwlua:uservalueinput|finenv.UserInputValue() dialog boxes]], except that there's generally no quotation marks around the strings and no ''{}'' around lists.
+//Lists// (except for ''NumberedList'' items) and //init values// are optional for parameters.
 ==== Handle Parameter in the Script ====
+A few lines of code are required to handle parameters sent to the script. Always make sure that the script can run without sent parameters as well.
+<code lua>-- Default values, if no parameters were sent to the script
+local resizestyle = 2
+local relativeresize = true
+-- Check if parameters were sent to the script.
+-- If that's the case, use those values instead.
+local parameters = {...}
+if parameters[1] then resizestyle = parameters[1] end
+if parameters[2] then relativeresize = parameters[2] end</code>
