[John W. Hamm]

You may ignore it and it will simply take the place of the one you see in your game up until this point, (its refering to the way your crews 2d pictures look well as , medals and rank insignia that are displayed in the Subs Crew management screen F10) try the new one and see which you like best, if you don't like the one in the mod just delete the "Menu" file in the mod and it will not ask which you want to use. however if you like the one in the mod better than let it substitute it for your old one next time you activate the mod. its all in the read me.
