as title.
say i want to add ladder.mod support.

first.create a jason file name
"PrefabGroupSpecification.Buildings.GreedyBuilders.optional.json"

put it under GreedyBuilderslocaction\Specifications\PrefabGroups



{
"Id": "Buildings.GreedyBuilders",
"Paths#append": [
"Tobbert/Ladder.IronTeeth"
]
}


you need to find the path for the build you wan to add.
that can be found in modyoulike\Specifications\PrefabGroups

in this case the path is
"Tobbert/Ladder.IronTeeth"

add these to your greedybuilder.jason.

they it should be working.
