-Multiple options are separated by semicolon: `key1=value1;key2=value2`.
+To specify multiple options add multiple `/overrideconfig [key=value]` entries:
+`/overrideconfig key1=value1 /overrideconfig key2=value2`.
 
 To have **space characters** as a part of `value`, `value` has be enclosed with double quotes - `key="My value"`.
 
 Double quote character inside of the double quoted `value` has to be be escaped with a backslash '\\' - `key="My \"escaped-quotes\""`.
 
-If closing double-qoute character is missing, it will be implicitily added at the very end of the command line argument - `key="My Value;key2=2(")`.

 Following options are supported:
 1. `assembly-file-versioning-format`
 1. `assembly-file-versioning-scheme`
