 In this case:
 
-- `PARAM1` is uncommented (if needed) and set with `value string "here"` (replacing any existing values if they exist)
-- `PARAM2` is uncommented (if needed) and set with no value string (any existing values are removed)
+- `PARAM1` is uncommented (if needed) and replaced with `value string "here"` (replacing any existing values if they exist)
+- `PARAM2` is uncommented (if needed) and replaced with no value string (any existing values are removed)
 - `PARAM3` is uncommented (if needed) and leaving any existing value string in place
 - `PARAM4` is commented out
+- `PARAM5` is added to the document regardless of the existence of the parameter. You can use this to add the same parameter multiple times
