# Defining Tribes¶

Each tribe is bootstrapped with the following scripts:

• data/tribes/init.lua: This file loads all the scripts that define the tribes. So, if you add a new tribe or a new unit to a tribe, it needs to be listed in this file.

• data/tribes/preload.lua: Provides basic information about all available tribes to the game launching screens. The player won’t be able to select a tribe without it being defined in this file.

• data/tribes/<tribe name>.lua: These scripts tell the engine which units belong to each tribe. They also define some global animated images for each tribe (flags, borders, roads).
