Under Review

This tutorial or guide is currently undergoing review and should not be considered ready to use.

XML Definitions (or just "Defs") are used to add new content to RimWorld. This includes weapons, apparel, equipment, animals, mechs, plants, and many other things.

Folder Location

Defs are placed in XML files in the Defs folder of the standard mod folder structure. The exact paths and file names do not matter except for LoadFolders loading within your own mod; you can name and organize your files however you want for your own organization.

You can also find vanilla's Defs in [your Steam folder]\common\RimWorld\Data. You can and should reference vanilla Defs as templates and examples when creating your own. Loading the Data folder into the code editor or IDE workspace of your choice for faster searching is also strongly recommended.
