Cards for your army list
A printed datasheet is most useful when it shows only what the unit on the table actually has.
Add the units
Pick your faction on the left of the card maker and add each unit in your list. Units you field twice can be one card with two copies, or two cards if they carry different wargear.
Trim the weapons
A datasheet lists every option. In the editor, remove the ranged and melee profiles your models are not equipped with. The remaining rows get bigger text.
Set the colours once
Every faction starts with its own two colours. Change them on one card and press "Apply to all" to recolour the whole set.
Keep a backup
Export downloads one file with all your cards. Import it on another computer or after clearing your browser.
