spawn rate help plz?

so i downloaded a mod called Indominus Rex, and on that page it gave me a code to change the spawn rate of that indo rex, is there a way to add it to the ASM? if not then where would i put that code?


here is the code:


[Custom Spawn Rates]



DinoSpawnWeightMultipliers=(DinoNameTag=Indom,SpawnWeightMultiplier=0.05,OverrideSpawnLimitPercentage=True,SpawnLimitPercentage=.01)
