Guide To Contributing
Code: When adding code, follow the regular Urist guidelines and file structure. It makes things easier to keep track of. So, for adding anything self contained, go to code/modules/urist/40k and put it under the relevant subfolder. When adding items with in_hands, make sure to set urist_only = 1. When adding clothing, make sure to set the icon_override to the proper uristmob file. When adding clothing, make sure to make the path a child of the existing urist objs. This will take care of the above. Example: /obj/item/clothing/under/urist/itemgoeshere
Icons: We will also be following Urist guidelines. So, all icons go to the relevant subfolder under icons/urist/40k. All mob/in_hand icons go to the relevant .dmi under icons/uristmob as per usual.
