I'm confused? I am trying to add a Victoria 4 custom morph injection I created in another program. I folowed  A Gentlemuses's advice about adding V4 but when you say fill in the blank spaces there is a area to fill in: 
Library Name

• The name to be displayed in the Link Libraries listbox
• Also the name of the .ill file to be saved in the libs folde

What do I put in there? 
Do I change anything in the Delta or visisbilty boxes or just leave the defaults as they apprear?
Sorry it's probably obvious but I'm stumped.
Any help woudl be appreciated.
Thanks!
